摘　　要：针对齿轮等具有凹凸结构的工件对感应加热淬火的特殊要求,同步双频感应加热电源应运而生。同步双频感应加热齿轮淬火不仅精简了齿轮的制造工艺,也降低了能耗,提高了效率。对感应加热电源及同步双频感应加热电源进行了研究,详细分析了同步双频感应加热电源的电路结构及应用优势,并进行了理论分析和仿真研究。采用1台MPS系列MOSFET高频感应加热电源以及1台IPS系列IGBT冲频感应加热电源搭建试验台,对一件12齿的齿轮工件进行同步双频感应加热的试验,验证了该双频拓扑结构和参数的正确性,得到的电路波形与仿真波形基本吻合。Due to the surface character,the gear industry has special requirements of the induction heating quenching. With the advantages of small deformation and high productivity,the metal workpiece surface hardening is widely used in industry,which greatly simplifies the gear manufacturing process,reducing costs and energy consumption.The simultaneous dual frequency method of inductive gear hardening has great significance.This paper introduces the induction heating power supply and simultaneous synchronous dual-frequency induction heating power supply,analyzing the circuit and application benefits of simultaneous dual-frequency induction hardening,and ends with the academic analysis, simulation by Simulink/Matlab,and practice experiment.The experiment is done by a MOSFET high-frequency induction heating power supply and a IGBT medium-frequency power supply.The results are very fixed with the simulation, and this dual frequency induction heating power supply can work very well under safe and reliable operation.
