Abstract

Abstract

In order to solve the problem of voltage conversion accuracy deterioration caused by transformer interturn capacitance, this paper analyzes the influence of parasitic capacitance associated with the winding of a transformer on transformer output misalignment, puts forward a method to eliminate or adjust parasitic capacitance influencing factor and resonant frequency point by combining theoretical analysis with circuit simulation, and proposes an equivalent negative capacitance generation circuit. An output comparison carried on an equal turn ration transformer before and after the improvement verifies the feasibility of the method.
