Abstract

Abstract

In this paper, the LCC resonant converter for high voltage applications is analyzed and studied. The equivalent model is derived by the fundamental approximation method. The large signal model of the resonant circuit is established. Based on the equivalent model and the large signal model, the LCC resonance is performed. A parameter design method is proposed after analyzing the steady-state characteristics of the converter. The method can realize zero voltage switching of the resonant converter while taking into account the influence of the resonant current on the efficiency. Based on the large-signal model, a small-signal model is established to obtain a transfer function between the output voltage and the input duty cycle, thereby establishing a closed-loop system and achieving a wide-range output voltage. The Simulink simulation verifies that the designed LCC resonant converter can realize ZVS switch with full load range, which verifies the feasibility of the design method.
