Abstract:
A 4.5 kV double-gate (DG) reverse-conducting (RC) press-pack (PP) injection-enhanced gate transistor (IEGT) was developed. The DG-RC-PPI (PP-IEGT is abbreviated as PPI) was designed to control two kinds of gates in a DG-RC-IEGT device without chip-to-chip imbalance or interference between the gates. The fabricated DG-RC-PPI was examined under a switching condition of VCE=2800 V, IC=2100 A. By applying gate control, turn-off switching loss and reverse-recovery loss were reduced by 30% and 18%, respectively. As a result, we succeeded in reducing total switching loss by 16% compared with a conventional single-gate PPI.
