摘要
提出了一种中小功率绿色模式开关电源设计,该电源采用两级变换器分别对输入电流波形整形和快速调节输出电压。采用过渡模式有源功率因数校正、准谐振变频控制功率隔离变换和同步整流等多种先进的电源控制技术以降低电源的总机损耗,提高系统效率,减少谐波污染。测试结果表明该开关电源达到了绿色设计目的,可满足高性能应用的需要。
A novel green mode switching power supply is developed. It employs two stages of converters to shape the input current waveform and quickly adjust the output voltage, respectively. Some advanced power supply control approaches, such as transition mode PFC control, pseudo-resonant type power supply control and synchronous rectification, are adopted to design a power supply with lower power loss, high efficiency and less resonant current. The test results show that the green switching power supply is implemented and can meet the requirements for high performance.
