Abstract
This paper investigates the utilization of a planar Rogowski coil located between the dc-bus traces to measure the half-bridge’s switching transient current. The sensor’s fundamentals are explained, and design considerations are derived from a comprehensive parametric study analyzing the impact of a non-uniform dc-bus current distribution on the sensor’s mutual inductance. A compact current sensor prototype is designed and fabricated for a SiC MOSFET half-bridge application. Simulations show a minimal increase in the current communication loop stray inductance of 399 pH. The current sensor’s performance is experimentally validated with double pulse tests.
期刊介绍：
COMPEL exists for the discussion and dissemination of computational and analytical methods in electrical and electronic engineering. The main emphasis of papers should be on methods and new techniques, or the application of existing techniques in a novel way. Whilst papers with immediate application to particular engineering problems are welcome, so too are papers that form a basis for further development in the area of study. A double-blind review process ensures the content''s validity and relevance.
