摘　　要：本文从实际应用出发,针对商用电磁炉的电路拓扑,采用串联谐振方式详细分析了其不同的工作状态,得出逆变器功率器件的最佳开关过程,并从理论上计算出了频率和相角的关系,通过“脉冲宽度调功方式”与“锁相环控制”相结合的方式实现功率调节。在此基础上,搭建了一台串联谐振逆变器试验样机,进行了试验验证。验证结果表明,本设计有较好的应用前景。Based on the practical application,the article uses a series resonance method for the circuit topology of the commercial induction cooker,analyzes its different working status,and obtained the optimal switching process of the inverter power devices,theoretically calculated the relation between frequency and phase angle.The power regulation is achieved by a combination of“pulse width modulation(PWM)mode”and“phase-locked loop control”.Based on this,a series resonant inverter test prototype is built and verified the conclusion by experiments.It has a strong application background to solve practical problems.
