A ZVS Multi-Resonant DC-DC Converter (MRC) can be operated at high switching frequency. The MRC circuit can reduce the switing-loss and the effect of EMI, becouse it can absorb parasitic reactance into the resonant circuit and can prevent parasitic oscillations. However the conventional MRC circuit has some disadvantages such as control characteristics are non-liner.
In this paper, we describe the new MRC circuit which has two switcing-devices and two capacitors of the same capacitance. The output voltage of the new MRC can be controled from zero to the DC source voltage at both of posssitive and negative load-current.
