In-situ measurement for drain current of SiC-MOSFET using optical-probe current sensor with half-open loop magnetic yoke

In recent years, the switching frequency of power converters has increased significantly with the widespread adoption of wide-bandgap power semiconductors. Conventional sensors, such as current transformers and Rogowski coils, are limited by their size and frequency bandwidth, making accurate current measurement diffic...
