【摘要】 本文提出一种基于输出本质安全要求的改进型Boost变换器。当其输出出现短路故障时,通过控制隔离开关的关断和主开关的导通,可彻底切断输入电源并旁路电感能量,阻止电源和电感能量传输到输出端。实验结果证明了分析的正确性和改进方案的可行性。更多还原

【Abstract】 This paper presents an improved Boost converter based on the output intrinsic safety. The input power supply as well as the bypass inductance energy can be thoroughly cut off by controlling the shutoff of isolating switch and the turn-on of the master switch so as to prevent the power supply and inductance energy from transforming to the output end. The experimental result proofs the correctness of the analysis and the feasibility of the improved methods.更多还原
