Fixed pulse patterngate control uses optimum gating sequences to almost eliminate switching losses in the IEGT device. Gating sequencesare pre-computed for the control rather than computed at runtime. The result is performance that reduces losses andharmonics.Input CurrentDiode CurrentIEGT CurrentOutput Voltage10Conventional PWMFixed Pulse Pattern Control
