摘要
本文在对500 kWIGBT并联谐振感应加热电源所采用的并联型逆变器过流、过压保护电路,过流、过压检测原理进行分析的基础上,给出了逆变器过流、过压保护控制流程,在过压保护电路中设计加入了箝位电路。通过对保护系统模块比较完整的仿真建模和分析,研制了500 kW IGBT并联型感应加热电源,验证了所设计保护电路、控制方法的正确性和有效性。
In this paper, based on the analysis of over-current and over-voltage protection circuit of 500 kW IGBT parallel resonant induction heating power supply device,and the detection principle of over-current, over-voltage, gives the control flow of inverter＇ s protection of over current and over voltage, joins the clamp circuit into the ver-voltage protection circuit.Through the simulation modeling and analysis of the protection system module, 500 kW IGBT Parallelparallel resontant induction heating power supply device is developed, and tested in terms of the correctness and validity of the designed control mested.
