Abstract: A power electronics module (PEM) is constructed to convert electricity from an input form to an output form. Electrical power conversion subcircuits having input and output ports are positioned proximal to a front mounting plate. Rigid conductor elements having respective preformed shapes are constructed to electrically interconnect the subcircuits at input and output ports thereof to form a power conversion circuit selected from among multiple power conversion circuits configurable solely by selection of the conductor elements. Other preformed conductor shapes are constructed to interconnect input and output ports of the selected power conversion circuit to ports disposed on a rear mounting plate. A controller is mechanically coupled to the front mounting plate and constructed to operate the semiconductor switches in a prescribed timing that converts the electricity of the input form to the electricity of the output form by the selected power conversion circuit.

Abstract: A motor driver for driving a motor is disclosed. The motor driver has a first power bus, a first switching device coupled between the first power bus and a first terminal of the motor, a second power bus, a second switching device coupled between the second power bus and a second terminal of the motor, and an integrated braking chopper coupled between the first and second power buses. The integrated braking chopper is configured to dissipate an extra power generated by the motor.
