Study on a New Method of Voltage-Source Induction Heating Load-Matched

In this paper, the static characteristics of three types of circuit topology used for voltage-source induction heating static electricity induction load-matched are analyzed. The systematic analyzed results are given, with regard to the transforming range of load resistances, the circuit responding sensitivity to the variation of the inductor coils' parameters, and the voltage and current of each compensatory element enduring. According to theoretical analysis, the applied conditions of every compensatory circuit are pointed, as well as the merit and demerit of different topology. The rationality of the theoretical analysis is proved by simulation. The matching experimental results of typical induction coils are given at last. With the practicality of analysis illuminated, the consistency of simulation results with actuality is testified.
