Tuesday, February 23rd, 2016

IX2120B Drives Both High Side and Low Side IGBTs or MOSFETs

IXYS Integrated Circuits Division (ICD), Inc., a wholly owned subsidiary of IXYS Corporation (NASDAQ: IXYS), announced the immediate availability of the IX2120B 1200V Half Bridge Gate Driver IC.  The IX2120B is a high voltage IC that can drive discrete power MOSFETs and IGBTs that operate up to 1200V.  Both the high side and low side outputs feature integrated power DMOS transistors that are capable of sourcing and sinking 2A of gate drive current.

High voltage level-shift circuitry allows low voltage logic signals to drive IGBTs in a high side configuration operating up to 1200V.  The IX2120B’s 1400V absolute maximum rating provides additional margin for high voltage applications.

“This product complements the full selection of power driver ICs that we have developed and introduced to the power management market in the last 3 years. It is designed and produced in our internal wafer fabrication facility on the proven advanced SOI process,” commented Dr. Nathan Zommer, CEO and CTO of IXYS Corporation.

With the IXYS power MOSFET and IGBT products, the ICD drivers offer IXYS’ customers the whole system solution in a one-stop shop which includes the Zilog line of MCUs.

The IX2120B is manufactured on IXYS ICD’s advanced HVIC Silicon on Insulator (SOI) process, making the IX2120B extremely robust and virtually immune to negative transients and high dV/dt noise.

The inputs are 3.3V and 5V logic compatible.  Internal under voltage lockout circuitry for both the high side and low side outputs prevents the IX2120B from turning on the discrete power IGBTs until there is sufficient gate voltage.  The output propagation delays are matched for use in high frequency applications.

The IX2120B can drive power discrete MOSFETs and IGBTs in half-bridge, full-bridge, and 3-phase configurations. Typical applications include motor drives, high voltage inverters, uninterrupted power supplies (UPS), and DC/DC converters.  The IX2120B complements IXYS ICD’s extensive portfolio of high voltage gate drivers, low side gate drivers, optically isolated gate drivers and the full range of IXYS power semiconductors.

This IX2120B is available in 24-pin SOIC package.

Smart Energy Grids Integrating Renewables Require New Local-Storage Technologies

Friday, February 19th, 2016

Supercapacitors paired with microcontrollers forge an intelligent power-management solution for distributed networks.

As we modernize our power grids, we become increasingly reliant on Smart Energy, which integrates renewable energy generators to improve reliability and resource efficiency on distributed power networks. At the same time, we need to move toward a better energy-storage technology that’s cleaner and lasts longer than lead-acid batteries. The emerging class of hybrid supercapacitors are superior to lead-acid batteries in both respects. To function on a smart grid integrating locally stored power seamlessly for the user, supercapacitors require embedded controls to balance power production on a distribution network based on supply and demand.

ZigBee mesh networks for Smart Energy are an important and well-established market for embedded control. But with the explosive growth of distributed power networks and power-backup systems for mission- critical applications, Smart Energy storage is playing a pivotal role in expanding the makeup of today’s complex power grid. This key role presents a great opportunity to developers of embedded electronic sensors and controls.

Good-bye to “Battery Shortfalls Included”?

Local customer storage of both on-grid and renewable energy has evolved from electrochemical energy storage to alternative technologies for safety, environmental, cost and regulatory reasons. Off-grid and localized microgrids, which operate either in parallel or autonomously to mitigate disturbance on the grid, share similar storage and load-leveling Smart Energy needs. Though time-tested lead-acid batteries are robust and simple from the standpoint of electronic control, they’re unreliable due to a short lifespan of two to three years. And their toxicity makes them environmentally unfriendly.

Similarly, new paradigms have emerged as alternatives to traditional battery-based transportation methods such as Wayside Energy Storage systems, which are substations that buffer power for electric rail applications. Supercapacitors and on-train regenerative power-storage systems are challenging the cost of ownership of lead-acid batteries and the efficiency/cost of extended grid storage. Instead of transporting recovered energy through a low efficiency third rail to remote locations, light power-dense technologies such as hybrid-supercapacitors may be incorporated within the power-train to significantly reduce the transient delivery burden on the power grid.

For a grid increasingly powered by renewables, where timing of peak energy demand can further diverge from peak production, the need for local grid energy storage becomes an imperative. Opportunity has sprung up for safe and reliable power dense-storage solutions, along with better controls, sensors and feedback loops throughout the Smart Energy grids.

Today, alternatives such as mechanical flywheel and capacitive solutions address the shortfalls of lead-acid batteries and can anticipate greater inroads into these and other energy-storage markets. Capacitive solutions are especially interesting for peak power and energy storage applications in that they have the higher power and energy-delivery capabilities for a given volume, when compared to lead-acid batteries. They also have lifecycles that are two to three times longer and are eco-friendly and safe alternatives.

Achieving TCO Advantages

As often happens, the downside to integrating new technology is that more complex system controls and management are required to achieve a total cost of ownership advantage over existing solutions. Hybrid-supercapacitor solutions are no exception. Where older battery technologies are tolerant of over-charge, new system controllers accommodate strict-use constraints while providing reliability monitors for state-of-health and operational-condition communication for hybrid supercapacitors.

A simplified example of embedded control for stacked-cell energy systems is shown in Figure 1. To accommodate elevated voltages and energy requirements, either battery cells or supercapacitors are series-parallel connected to meet specifications. Inherently, cells in a series stack, in some applications supporting voltages up to 800Vdc, are mismatched with regards to their storage characteristics and require constant monitoring and control to ensure maximum storage capability, long life and safety. Specifically, the control processor function of Figure 1 must monitor for imbalance and redistribute energy within the stack when appropriate. The telemetric requirements for this system will include total capacity and capacity utilization, servicing requirements and fault conditions.

Indeed, if you think that Smart Meters are the only embedded process controls useful in grid power systems, think again! With the advent of Smart Energy, applications for process control abound in local power storage as we experience explosive growth in new energy models that bring with them rich opportunities for embedded control. You can liken this challenge to the evolution of power-storage solutions for mobile computing devices in the 1990s, where the need for new, safe and reliable power storage hastened in the era of fuel-gauges and smart-chargers, creating unparalleled opportunity for embedded controls that continues to this day.

Saelig Introduces Two LED-Warrior DALI Master Modules

Wednesday, February 10th, 2016

SAELIG_160210_lw09-02

Saelig Company Inc. (www.saelig.com) has announced the LED-Warrior09-01MOD and the LED-Warrior09-02MOD boards – DALI-Master modules with an I2C interface and two switch inputs. DALI (Digital Addressable Lighting Interface) is a building automation bus primarily for lighting control. This non-proprietary interface standard for dimmable electronic products offers greatly improved functionality and greater ease of use over conventional dimming and control methods.

The LED-Warrior09-01MOD board operates from an external 5V power supply, while the LED-Warrior09-02MOD derives its power supply from the DALI-bus.

The LED-Warrior09-01MOD is galvanically isolated from the DALI bus and can therefore be easily deployed as a bridge between two networks. It may be used as an I2C to DALI bridge, providing an interface to house bus controllers, single board computers, or other equipment, sending lighting control commands to a DALI bus.

The LED-Warrior09-02MOD is intended to connect simple switches and buttons to the DALI bus, or as a standalone device. The functionality of the switch inputs can be configured via the I2C-interface. Powered from the DALI bus, this version can supply up to 15mA at 5V to external circuits. It can turn conventional switches into DALI switches, or it can be combined with an RF module to function as a wireless to DALI bridge.

Applications in LED lighting control include dimming, switching, and recalling of preset light settings. Individual addresses, groups, or all connected equipment can be controlled on the DALI bus. All these functions can be programmed on the inputs, enabling a single button that dims a single luminaire, a group, or everything on the bus.

The LED-Warrior09 is also available as a DIL8 or SOIC8 integrated circuit.

These LED-Warrior DALI modules and ICs are designed by Code Mercenaries, a leading European supplier of industrial input devices and peripherals since 1998. Their design philosophy for LED lighting drivers is to deliver maximum efficiency and maximum life cycle to enable the potential of modern LED technology.

IXYS Releases 650V Ultra Junction X2-Class Power MOSFETs with Fast Body Diodes

Wednesday, February 10th, 2016

IXYS Corporation (NASDAQ: IXYS), a global manufacturer of power semiconductors and integrated circuits (ICs) for energy efficiency, power management, transportation, medical, and motor control applications, today announced an expansion of its Ultra Junction Power MOSFET product line: 650V X2-Class Power MOSFETs with fast body diodes. With on-resistance as low as 17 milliohms and current ratings ranging from 22A to 150A, these devices are optimized for soft-switching resonant-mode power conversion applications.

The intrinsic fast body diodes of the MOSFETs display very soft recovery characteristics, minimizing electromagnetic interference (EMI) especially in half or full-bridge switching topologies. With low reverse recovery charge and time, the body diodes can be utilized to make sure that all the energy are removed during high-speed switching to avoid device failure and achieve high efficiency.

Like other Ultra Junction MOSFETs from IXYS, these new devices have been developed using a proprietary process technology resulting in Power MOSFETs with significantly reduced on-resistance and gate charge. They also exhibit a superior dv/dt performance and are avalanche rated as well. Thanks to the positive temperature coefficient of their on-state resistance, they can be operated in parallel to meet higher current requirements.

Suitable applications include resonant-mode power supplies, high intensity discharge (HID) lamp ballast, AC and DC motor drives, DC-DC converters, robotic and servo control, battery chargers, 3-level solar inverters, LED lighting, and Unmanned Aerial Vehicles (UAVs).

These new 650V X2 Power MOSFETs with HiPerFET™ body diodes are available in the following international standard size packages: TO-220, TO-263, SOT-227, TO-247, PLUS247, TO-264, and PLUS264. Some example part numbers include IXFA22N65X2, IXFH46N65X2, IXFK120N65X2, and IXFN150N65X2, with drain current ratings of 22A, 34A, 120A, and 145A, respectively.
