What is a 3 phase PWM inverter?
Three-phase PWM inverters have a similar operating principle to single-phase inverters but use six power switches arranged in three legs. The control unit generates three separate PWM signals, one for each phase. These signals are used to control the switching of the IGBTs to produce three-phase AC power.
