一、概述最近几年,国外报道了电感变换器电源应用在空间、计算机及其外围设备和通信等领域。电感变换器电源在特殊场合,频率达兆赫范围,从而大幅度减小了体积和重量。虽然这种变换器对磁元件的要求与一般变换器不同,对半导体器件的要求也高一些,但仍然是值得推荐的一种电源电路。目前,采用脉宽调制的开关电路从原理上大致分为三类:(1)串联开关电路;(2)并联开关电路和电感变换器(即flyb-ack converter,它包括单管、双管等型式);
First, an overview In recent years, foreign reports of the inductor converter power applications in space, computers and peripherals and communications and other fields. Inductor converter power supply in special occasions, the frequency of megahertz range, thus significantly reducing the size and weight. Although this kind of converter has different requirements on the magnetic components than the general converters, the requirements on the semiconductor devices are higher, but it is still a recommended power supply circuit. Currently, pulse-width modulated switching circuits are roughly divided into three categories in principle: (1) a series switching circuit; (2) a parallel switching circuit and an inductance converter (ie flyb-ack converter Type);
