Induction Heating Appliances with Phase-Shifted Control Based on Time-Sharing Control

摘要

This paper proposes a new control strategy for LLC resonant inverter for induction heating appliances.This control strategy is a combination of phase-shift control and time-sharing control technique.The output power is controlled by using the phase-shift control method.Time-sharing control is used to increase the output frequency.With the use of shunt capacitors,the system can operate in soft switching.The validity of the proposed method is verified by MATLAB simulation.
