Abstract :
A novel "double phase-shift (DPS)" control for full-bridge (FB) three-level (TL) converter is proposed, which improves efficiency by reducing losses of switches\´ body diodes meanwhile maintains the converter\´s original advantages without adding additional components compared with "chopping plus phase-shift (CPS)" control. The operation principle is verified on 3 kW, 100 kHz prototype
