Pulse Injection Modulation Method for Current-Fed Dual Active Bridge Converter With Full Load Range ZVS Under Wide Input-Voltage Range
This letter proposes a pulse injection modulation (PIM) method for current-fed dual active bridge (CF-DAB). For the first time, the mechanism of zero voltage switching (ZVS) loss in all existing modulation methods of CF-DAB is revealed. PIM redesigns the modulation timing to overcome the inherent flaw of existing modulation methods, thereby achieving full-range ZVS, as well as low inductor current ripple, and voltage stress. The experimental results demonstrate that PIM offers higher efficiency and a wider input voltage range compared to existing modulation methods.
