一种新型多路输出反激式开关电源的设计和实现

Design and Realization of a New Kind of Multi-output Flyback Switching Power Supply

以UC3844PWM控制器为核心,设计了一种多路输出的单端反激式开关电源电路。该电源性能优良,具有稳压效果好,纹波小,负载调整率高等优点,可作为电机控制的电源模块,具有很高的应用价值。

By using UC3844 PWM controller as the core, one kind of switching power supply circuit which has a single flyback and multi-mute output is designed. This power supply has good performance such as high voltage stability, low output voltage ripple, good load adjustment rate and so on. It can be used for motor control as a power module and has better application value.
