ABSTRACT:
A power substrate module having a multilayer circuit board or laminated circuit board for use in a motor controller is described. The power substrate module includes pair of switching devices coupled across a direct current bus for converting direct current power from the bus to controlled alternating current power in response to control signals. The circuit board includes a first conductive layer, a second conductive layer and an insulative layer separating the conductive layers. The first and second conductive layers each include a conductive bus region, one of which is coupled to the first switching device and forms a high side of the direct current bus, and the other of which is coupled to the second switching device and forms the low side of the direct current bus.
