摘　　要：采用PI公司TOPSwitch—GX设计一种基于双极点补偿控制的反激式单片开关电源。文中阐述了主要设计步骤，为了提高电路控制系统的动态响应，采用双极点补偿反馈网络进行了设计改进，以进一步减小纹波，提高电源输出指标。经实际检验，该电源性能可靠，在工作现场能长时间稳定运行，具备良好的稳态性能和动态响应，达到了设计要求。The new TOPSwitch GX is an integrated switched mode power supply chip produced by Power Integration Corporation. In this paper, we introduce a special and auxiliary power supply for DSP with multiple outputs based on this chip and the main design procedures are expounded. In order to improve the dynamic performance, we implement the two-pole compensation network. The actual engineering tests show that this power supply is reliable even after a long time operation. It has high-level steady-state performance and good dynamic response and can satisfy the design requirements.
