高频变压器的设计是单端反激式开关电源设计的核心。如果在单端反激式开关电源中高频变压器的设计初步完成以后,不对高频变压器进行电路的仿真而是直接进行制作和实验调试,尽管最终可以得到实验所要求的各项性能指标,但是可能会花费大量的费用和时间。本文采用PExprt软件对单端反激式开关电源中高频变压器建立模型并运用PSPICE软件进行仿真,仿真结果表明本方法是可行的。
High-frequency transformer design is the core of single-ended flyback switching power supply design. If the single-ended flyback switching power supply in the design of high-frequency transformer is initially completed, the high-frequency transformer circuit simulation is not conducted but directly to the production and experimental debugging, although the final experiment can be required to obtain the performance indicators, but may It can cost a lot of time and money. In this paper, the PExprt software is used to simulate the high-frequency transformer in single-ended flyback switching power supply and the simulation is carried out by using PSPICE software. The simulation results show that this method is feasible.
