摘要
针对开关稳压电源存在的纹波问题,对降压型开关稳压电源拓扑结构中关键器件进行了研究,给出了减低纹波的策略,并对电路拓扑结构进行了研究,提出进一步降低开关稳压电源纹波的策略。
In view of the ripple problem in switching power supply,this paper studies the key components in the topology of buck switching power supply,presents a strategy of reducing ripple,studies the topology of the circuit,and proposes a strategy to reduce the ripple of the switching regulator power supply.
