设计并实现了一种简单易行且适用于连续电流和断续电流两种模式的变压器设计方法,并利用此方法对基于TOPSwitch-GX的多输出反激式开关电源变压器进行了设计研究。对电源的实验波形进行分析,结果表明,开关电源交流电压输入在86V^265V的范围内都能够稳定输出直流电压,说明此变压器设计方法可行,降低了计算难度,为反激式变压器的快速设计提供了便利。

A multi-channel output fly-back switching power supply based on TOP Switch-GX was introduced in the paper,and its transformer was designed by a simple and practical approach.The power test wave forms were analyzed.The experimental results show when the input voltage of AC switching power supply is within the range of 86V^265V,the DC voltage output of the multiplexer is stable,which proves this method is feasible.
