Abstract In Induction Heating (IH) cooking appliances more than one output is highly desirable. A three leg inverter is proposed for three output IH cooking application. It is operating with a constant frequency of 30.5 kHz and allows the power control in loads independently. On-off control technique in cyclic manner is used. The number of switching devices per load is two (i.e. one leg per load). Thus utilization of the switching devices is improved. It can be extended for more number of loads also. A 260 W prototype has been implemented. Experimental results have good agreement with the simulation results.

一种用于感应烹饪应用且具有独立控制的三输出逆变器

摘要 感应加热 (IH) 烹饪器具多于一个输出是非常需要的。建议为三输出 IH 烹饪应用使用三腿逆变器。它以 30.5 kHz 的恒定频率运行，并允许独立地对负载进行功率控制。使用循环方式的开关控制技术。每个负载的开关设备数量是两个（即每个负载一个支路）。因此提高了开关器件的利用率。它也可以扩展到更多数量的负载。已实现 260 W 原型。实验结果与模拟结果具有很好的一致性。
