Abstract

This paper proposes an improved partially interleaved structure for high-voltage (Several kV) highfrequency (Several hundred kHz) multiple output applications. Six structures are compared with the leakage inductance, AC capacitance and the rate of AC/DC resistance taken into consideration. The proposed structure features lower leakage inductance, smaller AC capacitance and lower rate of AC-DC resistance, which is suitable for high-frequency high-efficiency applications. A planar transformer with the proposed structure was built and tested in an LCLC resonant converter, where the input voltage is 40V, output is 4800V, switching frequency 500 kHz and the efficiency is 96.8%, which validates the analysis.
