Abstract

Magnetic integration can be introduced in contactless resonant converter with high-order compensation network, such as LCL and LCC, to reduce the number and volume of the magnetic components. However, the cross couplings among the multi-windings of the integrated contactless transformer will impair the performance of the converter. In this paper, an integrated LCL-S contactless resonant converter is proposed, and the detailed analysis including characteristics of input impedance, voltage gain, input current harmonics and capacitor stress are also given. An improved designing method to achieve a ZPA (zero phase angle) and load-independent voltage gain is presented. Finally, a 1kW prototype is built to verify the theoretical analysis. The analysis and experimental results reveal that LCL compensation with magnetic integration features lower voltage stress across the resonant capacitor.
