Passive lossless soft switching DC/AC converter design
Abstract
Due to the progress of science and technology, the traditional DC / AC converter gradually fade out of our sight, instead is semiconductor variable flow technology, made with the technology of DC / AC converter called static inverter.

DC/AC变换器的无源无损软开关设计
摘要
由于科学技术的进步,传统的DC/AC转换器逐渐淡出了我们的视线，取而代之的是半导体变流技术，用该技术制成的DC/AC变换装置称为静止变流器。
由于传统的变换装置体积较大并且质量比较重，已经满足不了其在各种场合下的需要，人们开始考虑如何来有效减小变换装置的重量和大小变器并提高其你变效率。一种有效的方案就是提高其电子器件的动作频率。但是提高器件的开关频率，又会给系统带诸如电磁干扰、开关损耗等不利影响。要想减小开关管的电磁干扰和开关损耗，可以通过限制过高的电流上升率和电压上升率来实现。
