An electric vehicle propulsion system having a motor with first and second electrically isolated windings and a system control unit for controlling the motor, wherein the system control unit includes a first power bridge for driving the first windings and a second power bridge for driving the second windings.

Electric vehicle propulsion system employing AC induction motor control

A power bridge assembly for providing electric current to stator windings of an electric motor used in an electric propulsion system for an electric vehicle. The power bridge is assembled on a laminated bus bar. An upper plate of the bus bar connects to one side of a high voltage battery, a lower plate of the bus bar connects to the other side of the high voltage battery, and an insulation layer is sandwiched between the upper and lower plates. Electrical switches and capacitors sandwich the laminated bus bar. With this structure, two fasteners, one for positive voltage and one for negative voltage, can connect the bus bar, capacitors, and switches both electrically and mechanically. The sandwich structure eliminates parasitic inductance from the electrical connections.

Three phase power bridge assembly

An electric vehicle power distribution module including a chassis containing electric power distribution components. A battery connector is disposed on the chassis for electrically connecting the power distribution components to a battery. A safety cover is secured to the chassis and includes an aperature in a side wall for receiving an electric cable from the battery to be selectively engaged with the battery connector. The aperture is positioned with respect to the battery connector so as to preclude removal of the safety cover from the chassis without disengagement of the electric cable from the battery connector.

Electric vehicle power distribution module

A high performance, high current, miniaturized low voltage power supply is disclosed which employs a thick copper-ceramic film primary board, a direct bonded copper secondary, flexible printed circuit power inductors, the power supply has high power leadless chip carriers, hybrid rectifier packages and various electrical circuits including application specific integrated circuits for control, a turn on protection and current sharing.
