摘要
针对小功率开关电源所普遍存在的问题,实现了一种新型小功率高频开关稳压电源的优化设计。本文采用Power Integrations公司推出的TOP244Y单片开关电源芯片,设计与制作了应用于变频器的辅助开关电源。实际应用结果充分体现了该开关电源体积小、可靠性高、稳压性能好等优势。
For the common problem of low-power switching power supply, this paper introduces an optimal design for a new low-power high-frequency switching power supply. This paper designs and makes a single-chip switching power supply based on Power Integrations Company＇s TOP244Y. The experiment shows that this power supply used in inverter has the advantages of small volume, high reliability, and good performance.
