This paper presents a single-stage AC–AC resonant converter configuration for different material vessel induction cooking. The proposed configuration features input power factor correction, boost operation, and integrated bridge inverter configuration for multiple loads. In this topology the inverter legs are operated at two different frequencies to power induction cooking loads of steel and aluminum vessels. The induction cooking loads are operated at frequencies closer to their respective resonant frequencies. The load powers are independently controlled by pulse frequency modulation (PFM) technique. The proposed topology eliminates the use of electromechanical switches. The proposed single-stage AC–AC resonant converter configuration has been tested with two different vessels of steel and aluminum. The simulation and experimental results of the proposed configuration are in good agreement. This topology offers the advantages of low component count, high efficiency, and suitability for different material induction cooking.

用于不同材料容器感应烹饪应用的单级脉冲频率控制 AC-AC 谐振转换器

本文介绍了一种用于不同材料容器感应烹饪的单级 AC-AC 谐振转换器配置。建议的配置具有输入功率因数校正、升压操作和多负载的集成桥式逆变器配置。在这种拓扑结构中，逆变器支路以两种不同的频率运行，为钢制和铝制容器的感应烹饪负载供电。感应烹饪负载以更接近其各自谐振频率的频率运行。负载功率由脉冲频率调制 (PFM) 技术独立控制。所提出的拓扑消除了机电开关的使用。建议的单级 AC-AC 谐振转换器配置已经用两种不同的钢和铝容器进行了测试。所提出的配置的模拟和实验结果非常一致。这种拓扑结构具有组件数量少、效率高以及适用于不同材料感应烹饪的优势。
