摘要

提出了一种基于内置变压器(BIT)的高升压DC-DC变换器。该变换器可以在不增加元件数量的情况下实现高电压。此外，该变换器采用了层间结构，使输入电流纹波较小。此外，由于无源箝位电路，功率开关和二极管之间的电压应力可以降低。同时，由于位元的漏感，不仅使mosfet在零电流开关(ZCS)性能下处于导通状态，而且使所有二极管都处于零电流开关(ZCS)状态。从而减小了功率二极管的反向恢复问题。根据上述优点，所提出的变换器是高功率应用的一个有趣的解决方案。为了验证所提出的变换器的性能，本文讨论了所提出的变换器在40-400V电压转换和600W额定功率下的PSIM仿真结果。

An Interleaved Non-isolated Step-up DC-DC Converter with Built-In Transformer For Renewable Energy Systems

This paper presents a high step-up DC-DC converter based on the built-in transformer (BIT). High voltage without more number of elements is achieved in the proposed converter. Moreover, the interlevead structure is used in this converter, causing low input current ripple. In addition, the voltage stress across power switches and diodes can be decreased, thanks to the passive clamp circuit. Meanwhile, due to the leakage inductance of BIT, not only turn-ON state for MOSFETS at zero current switching (ZCS) performace is provided but also ZCS turn-OFF state for all diodes is achieved.. Thus, reverse recovery problem of the power diodes is attenuated. Accroding to the above-mentioned advantages, the proposed converter is an interesting solution for high power applications. To verify the performance of the proposed converter PSIM simulation results of the proposed converter with 40-400V voltage conversion and 600W rated power are discussed in this paper.
