Abstract :
A resonant DC link scheme for soft-switched inverters is proposed, where the link oscillation can be synchronized with inverter modulation. The scheme is able to operate with reduced commutation losses at a high switching frequency. Synchronization compatibility allows the development of suitable modulation techniques, which ensure improved waveform accuracy. The system performance and control strategies are verified both by simulation and by experimental tests, confirming the effectiveness of the proposed scheme.<>
