一種單端正激式變換電路的研究與仿真

摘要：從理論上詳細分析了一種高可靠性單端正激式變換電路的工作過程，以及副邊考慮漏感和不考慮漏感兩種情況下電路工作情況的不同。并對其進行了仿真研究，給出了仿真波形。結果表明該電路可靠性高、輸入輸出相互隔離、輸出紋波小，是一種非常有使用價值的拓撲電路。 敘詞：DC/DC變換器 正激式變換器 漏感 磁勢平衡 Abstract：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.
