Abstract

This study investigates noise current propagation in a power module accompanied with its switching operation. The noise current can be estimated from the measured near magnetic field. The proposed measurement system is developed to identify the time-dependent near magnetic field distribution in a power module. The system scans near magnetic field spatially and acquires its time-synchronized frequency spectrum. Propagation of the noise current in the power module is visualized as a time series of the noise current spectrum distribution in the power module. The developed system can help realize electromagnetic compatibility (EMC) design of a power module.
