Abstract

A very fast-response transformer-isolated current sensing method, that is based on a sense resistor which can be of low value, e.g. the Rds(on) of a HEMT, is presented, analysed, simulated and tested experimentally. The objective of the work was to develop a solution to over-current protection of a ‘normally on’ GaN HEMT that is connected in series with a silicon MOSFET to convert the module into a ’normally off’ assembly. However, the proposed fast pulsed-current sensor is general, and as such can be applied in other applications.
