Influence of the Inductance Ratio in the Oscillating Circuit on the Load Characteristics of an LLC Resonant DC-DC Converter

This paper presents an LLC resonant DC-DC converter operating at a frequency above the resonant frequency. Based on a study using the first harmonic method, the main dependencies for the currents through the power devices have been determined. The load characteristics of the converter have been constructed. A methodology for its design has been proposed. The influence of the ratio of inductances in the resonant circuit of the resonant converter on the obtained load characteristics has been studied.

Abstract

This paper presents an LLC resonant DC-DC converter operating at a frequency above the resonant frequency. Based on a study using the first harmonic method, the main dependencies for the currents through the power devices have been determined. The load characteristics of the converter have been constructed. A methodology for its design has been proposed. The influence of the ratio of inductances in the resonant circuit of the resonant converter on the obtained load characteristics has been studied.
