分析了电压型感应加热电源利用静电感应法实现负载匹配的三种拓扑电路的静态特性。在负载电阻的变换范围内,对感应线圈参数变换的灵敏度、各补偿元件承受的电量值(电压、电流)等方面进行了系统的理论分析,并在此基础上指出了不同拓扑电路的使用条件和优缺点。最后通过典型感应线圈的仿真与实验,证明了分析的合理性和实用性。

The static characteristics of three types of circuit topology used in static electricity induction load-matching of voltage-source induction heating inverters are analyzed. Within the transform range of load resistances, the systematic analysis is made of the sensitivity of induction coil parameter transform and electricity values （voltage, current） of each compensatory element endurance on the basis of which the use conditions, and strong and weak points of different topology circuits are pointed out. Finally, the simulation via typical induction coils and experiment results have proved the analytical rationality and practicity.
