提出了一种新型辅助有源谐振电容缓冲辅助零电流软开关脉冲调制单端推挽(SEPP)串联负载谐振逆变器，该逆变器具有两个辅助谐振无损电感缓冲电路。用各模等效电路描述了其稳态工作原理。该新型多谐振高频逆变器基于不对称PWM控制方案，在恒频零电流软开关(ZCS)换相原理的基础上，实现了输出功率的调节。在实验结果的基础上，对采用ZCS-PWM系列负载谐振SEPP高频逆变器的消费类全新IH产品进行了评价和讨论，并与传统高频逆变器进行了比较。为了在低功率设定的脉宽调制下扩大零电流开关的工作范围，提出了高频多谐振逆变器的脉冲密度调制策略。从应用的角度充分证明了它的实际有效性
In this paper, a novel type auxiliary active resonant capacitor snubber assisted zero current soft switching pulse modulation single-ended push pull (SEPP) series load resonant inverter with two auxiliary resonant lossless inductor snubbers is proposed for consumer high-frequency induction heating (IH) appliances. Its operating principle in steady state is described by using each mode equivalent circuits. The new multi resonant high-frequency inverter can regulate its output power under a condition of a constant frequency zero current soft switching (ZCS) commutation principle on the basis of asymmetrical PWM control scheme. The consumer brand-new IH products using proposed ZCS-PWM series load resonant SEPP high-frequency inverter is evaluated and discussed as compared with conventional high-frequency inverter on the basis of experimental results. In order to extend ZCS operation ranges under a low power setting PWM, the pulse density modulation (PDM) strategy is demonstrated for high frequency multi resonant inverter. Its practical effectiveness is substantially proved from an application point of view
