Abstract This paper introduces a new kind of DC-DC converter used in the DC microgrid system.This converter embodies a high frequency DC transformer with Y-Δ structure.This transformer works at the phase shift mode,which can achieve higher voltage gain and is prone to magnetic integration.In the low voltage side we apply the current-triple rectifier circuit to achieve higher frequency and lower ripple of current,which can extend battery life.In the end,a 500 W prototype with DC input voltage of 12 V and output voltage of 380 V is built in the lab to verify the theory.When the converter works in the phase shifting control strategy,high voltage gain,high efficiency,and magnetic balance of the transformer can be realized.
