摘要： A busbar assembly includes a base having a width and a length. The base has a first surface and a second surface and has a first side and a second side. A distance between the first side and the second side comprises the width, and the base defines a slot centered between approximately 75% and approximately 79% of the width.

摘要： A motor control system includes: a d-q target module configured to, based on a target torque of an electric motor, determine a first target d-axis current and a first target q-axis current; an offset module configured to, based on a capacitor current through capacitors connected across phases of the electric motor, determine a d-axis current offset and a q-axis current offset; an adder module configured to determine a second target d-axis current based on a sum of the first target d-axis current and the d-axis current offset and to determine a second target q-axis current based on a sum of the first target q-axis current and the q-axis current offset; and a driver module configured to, based on the second target d-axis current and the second target q-axis current, switch switches of a current source inverter (CSI) module configured to apply power to the phases of the electric motor.

摘要： A current source inverter includes a first phase leg including a plurality of switching devices, a second phase leg including a plurality of switching devices, and a third phase leg including a plurality of switching devices. The current source inverter also includes a zero-state phase leg including at least one switching device, wherein the zero-state phase leg is configured to transition from an open state to prevent current flow to a closed state to allow current flow between a positive and negative terminal during a dead-band time.

摘要： A planar power module includes a second substrate arranged parallel to a first substrate, with the substrates respectively having a dielectric layer interposed between two conductive layers, such that one of the conductive layers of each substrate together forms parallel external conductive surfaces of the power module. The power module includes direct current (DC) bus bars, alternating current (AC) bus bars, and semiconductor switching dies arranged between the substrates. The dies are electrically connected to the bus bars, with each respective die electrically connected to a conductive layers of the first or second substrates. A polymer molding material partially surrounds the substrates and the switching dies. An electric powertrain system includes an electric machine, a propulsion battery pack, and a traction power inverter module (TPIM) having the power module. The power module is a three-phase full-bridge inverter circuit. An electric powertrain and motor vehicle use the power module.
