Abstract :
A simple resonant link inverter is proposed to achieve pulsewidth modulation operation by using a single set of auxiliary resonant circuits which provides the soft-switching function to all main switches. With the proposed circuit, the clamped output link voltage, soft switching of all switches and reduced current stress on the resonant switch can be obtained
