Research on parallel resonant inverters power's expansion of high-power and frequency induction heating power supply

大功率高频感应电源大多采用多个逆变器并联来提高整机的功率,针对大功率电源LC谐振逆变器与LLC谐振逆变器,对并联逆变器之间的均流情况与工作特性进行了理论、仿真研究与实验分析,并提出了相应的措施以实现并联逆变器之间的均流。

Several paral el inverters were adopted by high-power and frequency induction heating power supply to increase the machine＇s power. According the LC series resonant inverter and LLC resonant inverter of high-power supply, detailed theory, simulation study and experiment analysis on the current sharing between paral el inverters and characteristics were made. And the corresponding measures to keep the current balance between the paral el inverters were put forward.
