摘　　要：为了实现对工件的梯度加热,需要采用多个感应线圈对工件进行分段加热。针对多个感应线圈之间存在功率耦合的问题,采用解耦控制策略对耦合系统进行控制。设计了两级式感应加热电源耦合系统实验样机,并对耦合系统中主机、副机的控制设计进行重点介绍。仿真分析和实验结果表明,耦合系统中主机、副机可以实现功率独立输出。In order to actualize gradient heating on the workpiece,multi-inductor heating the workpiece by segmented was required.Aiming at the existence of power coupling between the inductors,the decoupled control strategy was built in coupling system.A experimental prototype of two-stage induction heating power supply coupling system was designed,then the control design for the master and slave inverter was described detailedly.The simulation analysis and experimental results show that the master and slave inverter can realize output power independently.
