Research and Simulation of a Single-ended Forword Converter

从理论上详细分析了一种高可靠性单端正激式变换电路的工作过程,以及副边考虑漏感和不考虑漏感两种情况下电路工作情况的不同。并对其进行了仿真研究,给出了仿真波形。结果表明该电路可靠性高、输入输出相互隔离、输出纹波小,是一种非常有使用价值的拓扑电路。

Working process of a highly reliable Single-Ended Forword Converter is analysed in detail theoretically, and it is also analysed the difference of working condition in two cases, secondary side without leakage and with leakage. A simulation research is conducted targeting at this kind of circuit. And emulational waveforms are given. The research shows that the circuit is highly reliable; its input and output are isolated; its output ripple is small. And it proves that it is a very valuable topological circuit.
