This paper presents a nonisolated high step-up soft switching DC/DC converter with continuous input and output energy, low input current ripple, and low voltage stress of semiconductors. In this topology, passive clamping circuits are used not only to recycle leakage energy but also to successfully alleviate voltage spikes on the active MOSFET. The leakage inductor, on the other hand, solves the output diode's reverse recovery problem effectively. Furthermore, output capacitors are connected in series to supply the output load, resulting in a smaller output capacitor volume. The suggested topology's operational theory, as well as steady-state analyses, is thoroughly explored. The proposed topology's voltage gain and switch stress are then compared with that of some high-gain topologies. After this, a prototype circuit with a 20 V input voltage, 340 V output voltage, and 200 W output power is designed to test the proposed topology's accuracy.

基于三绕组耦合电感器和准谐振操作电压倍增器单元的单开关高升压零电流开关 DC-DC 转换器

本文介绍了一种具有连续输入和输出能量、低输入电流纹波和低半导体电压应力的非隔离式高升压软开关 DC/DC 转换器。在此拓扑中，无源钳位电路不仅用于回收泄漏能量，还用于成功缓解有源 MOSFET 上的电压尖峰。另一方面，漏感有效地解决了输出二极管的反向恢复问题。此外，输出电容串联为输出负载供电，输出电容体积更小。对建议的拓扑结构的操作理论以及稳态分析进行了彻底的探索。然后将所提出的拓扑结构的电压增益和开关应力与一些高增益拓扑结构进行比较。在这之后，
