摘要

为了满足DC/DC变换器中电感电流测量的高电压要求，提出了一种新型电流传感电路。所提出的电流传感电路基于匹配互补滤波器(MCF)技术。此外，该技术采用自举电路切断传感电路与地之间的通道，使传感电路的供电电压随其输入信号浮动。在输入35V，输出53V的DC/DC升压变换器上对该方案进行了验证，并给出了实验结果来验证理论分析。实验结果表明，该电路可以应用于高压系统。

A current sensing circuit with bootstrap effect for DC-DC converters

In this paper, a novel current sensing circuit is proposed to satisfy high voltage requirement in inductor current measurement for DC/DC converters. The proposed current sensing circuit is based on Matching Complimentary Filter (MCF) technique. Besides, the novel technique uses a bootstrap circuit to cut off the approach between the sensing circuit and ground, making the supply voltage of sensing circuit floating with its input signal. The proposed scheme is verified on 35V input with 53V output DC/DC boost converter and the experimental results are presented to demonstrate the theoretical analysis. The experimental results illustrate that the proposed circuit could be applied on high voltage systems.
