| Abstract: | In this paper, a new soft-switching inverter using a minimum number of devices, and a new PWM (pulse-width modulation) method
suitable for 3-phase soft-switching inverters are proposed. The circuit is used as an interface between the DC supply and
the conventional voltage source of a PWM inverter. The number of switching operations can be reduced by using the PWM strategy.
Increasing the amplitude of the fundamental component contained in the output waveform results in an effective utilization
of the DC supply, a reduction of nominated capacity of the inverter elements, and a reduction of switching loss in the switching
devices.
