摘要
本文介绍了一种新的并联逆变中频电源的起动方法——三桥臂起动法。文中说明了原有预磁化起动法的应用之所以受局限的原因,并详细分析了新方法的原理和应用方法,给出了多种模拟及实验波形,并且对其中的几个问题进行了讨论。理论分析及使用结果表明该方法具有较大优越性和实用价值。
A novel starting method-triple-arm method-for parallel-resornant medium frequemcy power supply is introduced. The paper explains why its counterpart-quadruple-arm method-is difficult to be used in applications, and describes the principle and the usage of this method. Results of stimulation as well as experiment under various conditions are given. Also, severtal problems are discussed. Theoritical analuysis and practical use ahows many advantages of the new method.
