Abstract
A system includes: an inverter configured to convert DC power from a battery to AC power to drive a motor, wherein the inverter includes: a power module including: a first phase switch including one or more first phase power switches on a first side of a substrate; and a second phase switch including one or more second phase power switches on a second side of the substrate opposite to the first side.
Claims17
A system comprising:
- an inverter configured to convert DC power from a battery to AC power to drive a motor, wherein the inverter includes:
- a power module including:
- a first phase switch including one or more first phase power switches on a first side of a substrate and one or more first thermal spacers on the first side of the substrate;
- and
- a second phase switch including one or more second phase power switches on a second side of the substrate opposite to the first side and one or more second thermal spacers on the second side of the substrate;
- wherein the one or more first thermal spacers are approximately aligned with the one or more second phase power switches, and the one or more second thermal spacers are approximately aligned with the one or more first phase power switches.

A system comprising:
- a power module for an inverter, the power module including:
- a first phase switch including one or more first phase power switches on a first side of a substrate, wherein the first phase switch is configured to be connected between a negative terminal of a battery and a phase terminal of a motor;
- and
- a second phase switch including one or more second phase power switches on a second side of the substrate opposite to the first side, wherein the second phase switch is configured to be connected between a positive terminal of the battery and the phase terminal of the motor.
1 more element
A system comprising:
- a power module for an inverter, the power module including:
- a battery side negative tab;
- a battery side positive tab;
- a motor side tab;
- a first phase switch extending along a first plane, the first phase switch configured to control a flow of current between the battery side negative tab and the motor side tab;
- and
- a second phase switch extending along a second plane, the second phase switch configured to control a flow of current between the battery side positive tab and the motor side tab,
- wherein the first phase switch is stacked on the second phase switch so that a normal vector from the first plane intersects the second plane.
