摘要
针对汽油变频发电机组中逆变器所需多组低压直流电源问题,设计了一种多路输出的开关辅助电源,结构简单紧凑、输出电压纹波小、体积小、成本低;通过分析高频变压器的设计原理,设计了一台功率为15W的四路直流输出的开关辅助电源;实验证明了该辅助电源的可行性。
With the aim of providing low DC sources in gasoline inverter generator set, the switching power supply with simple structure has been designed. Less ripple voltage, smaller in volume, lower cost are its features. On the basis of design principle of high frequency transformer, an accessory power supply ( 15W active power) with 4 sets of outputs is designed. The experimental results show its validity.
