浅谈高压变频器的原理及冷却方式

On the principle and cooling mode of high voltage frequency converter

主要论述了高压变频器的几种常见散热方案,随着电力电子技术的发展,变频器的应用愈加广泛,逐步向大容量及高电压迈进,高压变频器都以交流-直流-交流的转换形式居多,在转换过程中会产生大量的热量,只有将这部分热量耗散掉,才能保证变频器的安全稳定运行。

This paper mainly discusses several common heat dissipation schemes of high-voltage frequency converters.With the development of power electronic technology,the application of frequency converters is becoming more and more widely,and gradually moving towards high capacity and high voltage.High voltage frequency converters are mostly in the form of AC-DC-AC conversion,which will produce a lot of heat in the conversion process,which can only be dissipated,In order to ensure the safe and stable operation of the frequency converter.
