Abstract
This paper presents a new circuit topology of the half-bridge resonant inverter. As the proposed half-bridge inverter can be operated in the load freewheeling modes, pulse width modulation (PWM) control method can be used for the output power control. The proposed half-bridge inverter should keep unity output displacement factor under the load-impedance varying conditions, if a new PWM control scheme based on the resonant frequency tracking algorithm is adopted. In this paper, electrical characteristics, and losses analysis of the proposed half-bridge resonant inverter are described. Simulation and experimental results of the prototype experimental setup to verify the validity of the proposed half-bridge resonant inverter are presented and discussed.
