Simulation Design of a Multi-output Flyback Switching Converter

反激变换器在日常生活中得到了广泛应用,但是随着电子化设备的增多,直流多输出反激电源得到了广泛应用。因此,分析反激变换器的工作原理,设计了一种输出电压为±5 V的多输出反激式开关变换器,并在MATLAB/Simulink仿真软件中对设计的系统进行了仿真。仿真结果表明,输出的±5 V电压具有较好的动态性能,系统具有较好的稳定性,在实际应用中具有可靠性。

Flyback converter has been widely used in daily life,but with the increase of electronic equipment,DC multi-output flyback power supply has been widely used. Therefore,the working principle of flyback converter is analyzed, and a multi-output flyback switching converter with an output voltage of ±5 V is designed. The system is simulated in MATLAB/Simulink simulation software. The simulation results show that the output ±5V voltage has good dynamic performance,the system has good stability and reliability in practical application.
