Gate drivers from Power Integrations support ‘dual’ IGBT modules

Compact gate drivers based on Scale-2 technology make up the Scale-iFlex Single range from Power Integrations. The Scale-iFlex Single devices can be used with the popular “New Dual” IGBT modules, measuring 100 x 140mm.

Scale-2 technology optimises the footprint and improves efficiency, performance and reliability of power inverters and converters to 3,300V, says Power Integrations.

They support modules up to 3.3kV and are available now for design-in. The gate drivers can be used in a variety of high reliability applications, including light rail and renewable energy generation.

According to Thorsten Schmidt, product marketing manager at Power Integrations, “Scale-iFlex Single gate drivers fit the outline of the latest standard IGBT power modules, including the Mitsubishi LV100 / HV100, Infineon xHP2 and xHP3, ABB LinPak, Hitachi nHPD²”.

The Scale-iFlex Single gate drivers use Power Integrations’ Scale-2 ASIC technology, which reduces component count compared to conventional products, reported the company. The ASIC also provides advanced active clamping (AAC) over-voltage protection during normal operation, which is described as a “substantial improvement” over simple soft shutdown. It adds extra protection in case of short circuit event during turn on. Devices are conformally-coated and feature reinforced isolation. The isolated housings ensure modules can maintain isolation when they are mounted side-by-side. Devices are pre-qualified according to railway standards IEC 61373 – Class 1B (shock and vibration) and IEC 61000-4-x (EMC tests) and IEC 60068-2-x (serial environmental tests). Burn-in is optionally available.

The gate drivers are rated at 20A peak output current per channel at 85 degrees C ambient temperature with no air flow. Higher power levels are possible with cooling or a lower ambient temperature. Both electrical and fibre optic interfaces are available.

The Scale-iFlex Single gate drivers are available for sampling now.

Power Integrations specialises in semiconductor technologies for high-voltage power conversion. The company’s products are used in the clean-power ecosystem, enabling the generation of renewable energy as well as the efficient transmission and consumption of power in applications ranging from mW to MW.
