Abstract

In this paper, the reverse operating characteristics of LLC resonant converters from fr/2 to fr are explored. The reverse voltage-gain and the conditions for zero-voltage switching (ZVS) of the reverse LLC resonant converter are summarized, and the frequency interval is obtained according to the magnitude of the turn-off current. The accuracy of the above analysis is verified by experiments. The research on the reverse operating characteristics of LLC resonant converters has practical significance in some special applications especially when require for the bidirectional operation.
