Power Integrations introduces SCALE-iFlex Single plug and play gate drivers

Sep 18 2021 2021-09 Power Power Integrations

Power Integrations introduces SCALE-iFlex™ Single gate drivers for the popular "new dual-channel" 100mm x 140mm IGBT modules. The new compact driver supports modules with voltages up to 3.3kV and is now readily available for customers to complete design import. SCALE-iFlex Single Gate drivers are ideal for light rail, renewable energy generation, and other high-reliability applications that require compact, rugged drive solutions.

Thorsten Schmidt, Product Marketing Manager at Power Integrations, said: "The form factor of the SCALE-iFlex Single gate driver has been designed to fit perfectly with the latest standard IGBT power modules, These IGBT power modules include Mitsubishi LV100/HV100, Infineon xHP2 and xHP3, ABB LinPak, Hitachi nHPD² and others."

The SCALE-iFlex Single gate driver uses Power Integrations' SCALE-2™ ASIC technology, which significantly reduces the number of components compared to traditional products. Asics also provide advanced Active Clamp (AAC) overvoltage protection during normal operation, which is a great improvement over simple soft switch-offs, adding additional protection in the event of a short circuit during turn on. This product is treated with a triple resistant paint to provide enhanced insulation.

When modules are installed side by side, the isolated housing ensures safe insulation between modules. These devices have been pre-certified to the track standards IEC 61373-Class 1B (Shock and vibration), IEC 61000-4-x (EMC testing) and IEC 60068-2-x (a series of environmental tests). In addition, an aging test option is available.

The new gate driver has a rated peak output current of 20A per channel and a rated power of 1.5W MAG per channel at 85°C ambient temperature without air cooling (module for gate driver). Higher power levels can be achieved when air cooling is provided or at lower ambient temperatures. In addition, both electrical and fiber optic interfaces are available.
