Research on System Modeling and Starting Strategy of Inverter for Medium-Frequency Induction Heating

Aiming at the puzzle of being low in starting success rate and poor in starting performance of the current source medium-frequency induction heating power supply, the paper presented a novel starting control strategy based on energy pre-charge starting system. In the paper, it made the anatomy and study comprehensively on a variety of energy pre-charge starting methods, constructed the system model of energy pre-charge starting control, and put forward to the starting strategy based on the load capacitor pre-charged. The results of the starting control strategy simulation demonstrated that the constructed system model and the presented starting strategy are reasonable and feasible. The research results provide a novel reference method for solving the starting control of medium-frequency induction heating power supply.
