摘要
针对开关电源的特性,为了解决双端正激DC/DC变换器普遍存在的磁通阶段维持不理想的问题,提出了一种独特的磁通维持控制设计方案,首先对主电路、控制及自启动回路的结构原理进行了分析,介绍了励磁激流回路、控制及自启动回路的实现方法,并利用仿真波形及实验结果验证了设计和分析的可行性和实用性。
Aiming at the characteristics of switching power supply, this paper presents a unique scheme for magnetic flux maintenance and control in order to solve non-ideal magnetic flux maintenance and control problem in the double-ended forward DC/DC converter stage. The structural principle of main circuit, control and self-start loop is analyzed. The implementation method of exciting rapids loop, control and self-starting circuit is introduced. The simuiation waveform and experiment results show that the design and analysis are feasible and practical.
