Abstract in different language: This paper presents a new zero current switching bidirectional DC-DC converter for dual voltage automotive systems. The improved version of hard-switched DC-DC converter with an additional auxiliary resonant network, which is a combination of two auxiliary switches, two resonant inductors and two capacitors. The operating characteristics of this converter design is to transfer the power flow from low voltage to high voltage and vice-versa. The soft-turn on (ZCS) and soft-turn off (ZCS) operations are achieved by using two auxiliary resonant networks. In addition to that, the auxiliary switches obtain ZCS turn-on/ turn off operations, since additional losses are negligible. Minimized switching losses and improved efficiency are significant merits in this topology. The operation principles and design simulation analysis are reported in this paper in order to validate the theoretical analysis. The simulation of converter design is performed on 100/350V/500W converter system operated at 75 kHz switching frequency.
