一、概述正向单端变换器电源线路,有小的输出纹波,大功率管的使用无共态导通问题,电路明显地简单,频率效率均很高,变压器体积也不大。在高反压大功率开关管工艺较为成熟的今天,单管电路功率达500W将完全是可能的。因此,这种新型简单可靠的开关电源系统,在计算机供电和其他大型电子设备中,其使用价值是不言而喻的。虽不敢说最优越,但比桥式或半桥PWM电路,从成本和可靠性方面比较,有突出特点,这种电路有广泛的、光明的前途。
I. Overview Positive single-ended converter power lines, a small output ripple, the use of high-power tube no common-state conduction problems, the circuit is obviously simple, high frequency efficiency, the transformer is not large. In high-pressure high-power switch technology is more mature today, the single-tube circuit power of 500W will be entirely possible. Therefore, the new, simple, and reliable switching power supply system is self-evident in computer power supply and other large electronic devices. Although not dare to say that the most superior, but more than bridge or half-bridge PWM circuit, from the cost and reliability, there are outstanding features, this circuit has a broad, bright future.
