Abstract

In this paper, analysis and design of the LLC resonant converter with magnetic control for light electric vehicles (LEVs) application are presented. The magnetic control instead of the widely used frequency control or phase shift control is adopted for the LLC resonant converter to achieve a better performance. The magnetic components and electromagnetic interference (EMI) filter design are simplified due to the fixed frequency operation, and the constant switching frequency and duty cycle operation for the primary switches are achieved. Meanwhile, a design methodology for the LLC resonant converter with magnetic control for battery charger application is proposed; by carefully designing the resonant tank, zero voltage switching (ZVS) and zero current switching (ZCS) operation for semiconductors are guaranteed. An experimental prototype is built to verify the theoretical analysis.
