大功率医用电源变压器耐压测试浅谈

Dielectric Strength of High Power of Transformers Use for Medical

本文介绍一种方法,通过控制微处理器输出为标准正弦波,调制方式为SPWM,驱动IGBT以及所连接的变压器,实现大功率电介质强度测试。

This paper introduces a solution by controlled output of the microprocessor is standard sine wave, modulation by SPWM, drived IGBT and the transfomaers, dielectric strength of high power of transformers come true.
