New IGBTs convert more solar energy

By optimising the new IRGB40xxDPbF 600V IGBTs for the lowest combination of Total Switching Energy (ETS) and on-resistance when operated at 20kHz switching frequency, International Rectifier allows engineers to save cost and increase the efficiency of solar inverters and Uninterruptible Power Supplies (UPS).

Traditionally, IGBTs incur excessive switching losses at the frequencies used in UPS and solar inverters. By overcoming this drawback, IR enables higher power outputs and lower cost-per-Watt in solar applications, as well as longer-lasting backup power in UPS systems. Size reductions can also be gained through lower power dissipation.

The IRGB40xxDPbF IGBTs use the latest-generation field-stop trench technology to achieve this improved trade-off. Advantages include lower collector-to-emitter saturation voltage and ETS compared to Punch-Through (PT) and Non-Punch-Through (NPT) IGBTs. Co-packaged ultra-fast soft-recovery diodes further improve efficiency and also reduce EMI.
