摘要
针对开关电源在低输出电压时存在的问题,提出了将开关电源和线性稳压电源结合的电路拓扑。因其具有三电平和两电平电路的优点,故能克服上述问题。理论分析和实验研究结果证明了这些优点。
The problem of the switching power supply in the case of low output voltage is analyzed. The new circuit for switching power which combines the switching Power supply’s advantages with liner regulated power supply’s is presented. It can solve the problem for the circuit own the advantage of three level and two level voltage circuit. The advantages are proved by theoretical analysis and experimental result.
