How does a 3 phase inverter work?
In a conventional three-phase inverter, a phase leg with two switches is connected to each phase. The switches in these phase legs are generally controlled with pulse-width modulation (PWM). With PWM, the input voltage of the inverter can be chopped into discrete pieces, and thus form a desired output signal.

What is a three-phase inverter bridge?
System-Level Block Diagram of Three-phase PWM The three-phase inverter is the core of any AC motor drive. PWM pulses generated by the three-phase PWM drive the inverter bridge. The following figure shows the inverter bridge. Figure 1-2. Three-phase Inverter Bridge
Why are discontinuous PWM techniques used in three-phase inverters and active rectifiers?
The development of discontinuous PWM techniques in three-phase inverters and active rectifiers has allowed power electronics manufacturers to achieve significant improve-ments in the efficiency of the devices. The reduction in power losses is caused by an unmodulated period in the phase legs of a three-phase power converter.
