Patent ID: 8482904

Claim:
A power module operable for use within a vehicle to rectify a three-phase, AC input to a DC output, the power module comprising: a housing; a first input terminal, a second input terminal, and a third input terminal, each of the first, second, and third input terminals being disposed within the housing and operable to establish an electrical connection to one of three busbars carrying the AC input; a first output terminal and a second output terminal, each of the first and second output terminals being disposed within the housing, and operable to establish an electrical connection to any one of two busbars carrying the DC output; a rectifier disposed within the housing between the input terminals and the output terminals, the rectifier having a plurality of switches operably connected between the input terminals and the output terminals to rectify the three-phase AC input to the DC output; a shunt electrically disposed between the connection to one of the output terminals and at least one of the switches such that current flow through the one of the output terminals must pass through the shunt; a first shunt pin and a second shunt pin, each of the first and second shunt pins being adhered to the shunt at spaced apart locations; and a printed circuit board (PCB) having control electronics operable to control opening and closing of each of the switches and measurement electronics operable to measure a voltage drop between the first and second shunt pins.
