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

(Shown in red)Another mode is the Fixed Pattern type, providing voltage stability,improved harmonics and efficiency. The Fixed Pattern mode stabilizesline voltage by providing system VARs when line voltage is low anddrawing VARs from the system when the voltage is high. By convention,VARs from the system are (+) and cause the line voltage to drop whileVARs from the converter are (-) and cause the line voltage to rise. Therelationship of line voltage, loads MW and converter MVAR is shown bythe blue voltage lines depending on the measured line voltage.MVA vs. MW and Voltage11
