| 摘 要： | 电火花加工(EDM)是一个复杂的过程,加工过程要在击穿延迟、火花放电、消电离三种状态间快速变换,因此对EDM电源设计的要求比较高。LCC谐振变换器综合了串、并联谐振变换器的特点,当开关频率大于谐振频率时,表现出恒流源特性,适合于类似 EDM电源负载多变和加工电流恒定的要求。本文分析了LCC谐振变换器的工作原理,在仿真基础上设计了一台峰值电流为20A的 EDM电源原理样机,仿真和实验结果验证了LCC谐振变换器加工电流具有很好的动态特性及电流恒定特性,验证了参数设计的正确性。

| Abstract: | LCC resonant converter features a combo of a serial resonant converter and a parallel one. When LCC resonant frequency works beyond over the natural resonant frequency,the converter tends to act as a current source,and can be used for EDM power supply. This paper analyzes the principle of the LCC resonant converter through simulation. A theoretic prototype of 20A peak current is designed as an EDM power supply by LCC resonant converter. The experiment results are consistent with simulation results. It makes clear that this converter has good dynamic characteristic and can keep current invariable well. |
