本文提出了一种新型的辅助开关电容辅助的边缘谐振软开关PWM串联负载谐振高频逆变器与两个辅助边缘谐振无损电感缓冲器的小型消费者感应加热设备。用开关模式等效电路描述了这种高频逆变器的工作原理。这种新型的多谐振高频逆变器采用沟槽栅IGBT，在恒频边缘谐振软开关换流的原理下，采用不对称PWM控制方案，实现高频输出交流功率的调节。高频功率调节和实际功率转换效率特性的消费者全新的IH产品，使用建议的软开关PWM串联负载谐振高频逆变器进行评估。从应用的角度，通过仿真和实验结果，与传统的软开关高频逆变器进行了比较，讨论了新提出的软开关逆变器的实用有效性和运行性能
In this paper, a novel type of auxiliary switched capacitor assisted edge resonant soft switching PWM series load resonant high frequency inverter with two auxiliary edge resonant lossless inductor snubbers is proposed for small consumer induction heating appliances. The operation principle of this high frequency inverter is described using the switching mode equivalent circuits. This newly developed multi resonant high frequency inverter using trench gate IGBTs can regulate its high frequency output AC power under a principle of constant frequency edge-resonant soft switching commutation by asymmetrical PWM control scheme. The high frequency power regulation and actual power conversion efficiency characteristics of consumer brand-new IH products that use the proposed soft switching PWM series load resonant high frequency inverter are evaluated. The practical effectiveness and operating performances of the newly proposed soft switching inverter are discussed as compared with the conventional soft switching high frequency inverters based on simulation and experimental results from an application point of view
