Lower IGBT Switching Losses Save Energy

Saving 30% of the power lost normally from domestic solar-energy converters will significantly boost returns from renewable energy, and designers can now achieve this using a new series of IGBTs from International Rectifier.

The new 600V IGBTs are optimised for power-converter applications from 4A to 48A, and use IR’s latest-generation field-stop trench technology to reduce both conduction and switching losses. Designed for 20kHz operation with lower switching losses than standard IGBTs, the IRGB40xxDP series ensures high conversion efficiency to maximise energy sources such as solar panels or emergency back-up batteries.

Co-packaged with ultra-fast soft-recovery diodes, the new family of IGBTs has lower collector-to-emitter saturation voltage (VCE(ON)) and total switching energy (ETS) than Punch-Through (PT) and Non-Punch-Through (NPT) IGBTs. In addition, the internal ultra-fast soft-recovery diode improves efficiency and reduces EMI.
