Systems and methods for power module for inverter for electric vehicle

Abstract

A system includes: an inverter configured to convert DC power to AC power, wherein the inverter includes: a power module including: a flex layer including a gate trace providing an electrical connection to a gate input connection of the power module, a first substrate, a second substrate including a source plane, the source plane including a step trench, a semiconductor die disposed between the first substrate and the second substrate, the step trench formed in a portion of the source plane corresponding to at an edge of the semiconductor die, and the semiconductor die including a gate connected to the gate trace, and a sinter element disposed between the semiconductor die and the second substrate to connect the semiconductor die to the second substrate; a battery configured to supply the DC power to the inverter; and a motor configured to receive the AC power from the inverter.
