Abstract: Six sets of parallel-connected MOSFETs (e.g., 42-46) are gated to provide a 3-phase (26, 28, 30) output. At least one of the MOSFETs (48, 64, 66) 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.
