ABSTRACT:
Six sets of parallel-connected MOSFETs are gated to provide a 3-phase output. At least one of the MOSFETs in each of three sets of the six sets has a separately metallized current-sensing pad. The output from this pad represents the phase current. When phase current reaches a maximum permissible level, this signal controls the MOSFET gates to limit current.
