Modulation strategy of dual active bridge DC-DC converter for a complete zero voltage switching operation


A dual active bridge (DAB) dc-dc converter has a limited soft-switching range and high circulating current with the conventional phase shift modulation (PSM) when a voltage variation occurs in the input/output voltage. To overcome these issues, single pulse-width modulation (SPWM) and dual pulse-width modulation (DPWM) were proposed and combined into one… (More)
