| Abstract: | The main circuit operation of series load resonant induction heating power is analyzed and a method of frequen- cy tracking is presented.If the DC bus current is unidirectional,the induction heating power is operation in resonance frequency.The power supply based on DSP is designed and the controlling flow chart is proposed.The results shows this power works efficiently. |
