Characteristic Analysis of High Voltage Inverter on IEGT Five-pulse PWM Mode

The characteristic of power device IEGT and inverter that made up from IEGT was analysed.It provides rectification side input current wave of five-pulse PWM modulated mode and of triangle wave PWM modulated mode which eliminate particularly harmonics,electric source current the two modes were paralleled.The result shows that the inverter of five-pulse IEGT has good harmonics performance and high efficiency characteristic.It is a developing direction of high voltage big capacity inverter.
