N2 - In this paper, a novel switching scheme using discontinuous pulse-width modulation (DPWM) for a zero-voltage switching (ZVS) grid-connected three-phase inverter is proposed. ZVS in the main and auxiliary switches was achieved. Moreover, the reverse recovery currents of the anti-parallel diodes in the main switches were suppressed. A circuit analysis was performed, and a simulation was carried out. Furthermore, a prototype of the ZVS grid-connected three-phase inverter was constructed to verify the effectiveness of the proposed PWM control scheme. Both the simulation and experimental results verified the validity of the proposed PWM control scheme.
