Characteristic analysis of double PWM three-level inverter implemented by IEGT

The text aims at the harmonic pollution and powerless of the electronic network caused by inverter. Based on the foundation of power device IEGT and dual-PWM three-level inverter characteristics, the contrast of the rectifier three-pulse PWM modulate mode and the triangle PWM modulate mode is given. As a result, IEGT dual-PWM three-level inverter possesses the characteristics such as the good input and output wave type, the high power factor, the high efficiency and etc.
