Development of Ultra-Small Current Sensor for High-Voltage Power Semiconductor Modules : Proposal and Demonstration of the Noise Reduction Structure

摘要

We designed and demonstrated the ultra-small PCB current sensor for monitoring chip current in the high-voltage IGBT module. Based on the previous researches, here we adopted a design to remove noise influence. Taking advantage of the electric field shield and the small coaxial connector, the effect of noise removal was achieved.
