The difference between a hard switching and quasi resonant flyback converter is the turn on time point of the primary switch. 硬开关和准谐振反激变换器之间的差异在于一次侧开关的开启时间点。
An active-clamp flyback converter circuit is presented to realize Zero-Voltage and Zero-Current Switching ( ZVZCS) transition and at the same time suppress the voltage spike. 本文采用有源箝位反激式变换器电路,实现了零电压零电流(ZVZCS)软开关变换,使电压尖峰得到了抑制。
In this article based upon requirements on the power supply of automatic fire warning control system a single-end flyback switching power supply is designed; at the same time a new fault detection method is proposed for power supply. 介绍了开关电源的优点及分类,从火灾自动报警控制系统对电源的要求出发,设计了一种单端反激式的开关电源,提出了一种新的电源故障检测方法。
