บทคัดย่อ
The variable-frequency asymmetrical voltage-cancellation (VFAVC) control is proposed in this paper to control the output power for a series resonant load with a full-bridge inverter for home appliance as induction cooking. The asymmetrical voltage-cancellation is used for controlling the output power. With the low quality factor loads, a fixed-frequency control might lead to non-zero-voltage-switching (NON-ZVS) operation. The proposed control strategy ensures the ZVS operation for switching loss reduction by varying the switching frequency slightly higher than the resonant frequency. By using the ZVS constant, the new control strategy is proposed by varying the switching frequency according to the output power. Moreover, this proposed control can improve the overall efficiency of inverter system. The experimental results are given in this paper to verify the proposed control method. ฉ 2011 IEEE.
