1. A system for an electric vehicle, the system comprising:
an inverter housing including an inner wall, a first channel, and an exterior surface;
a heatsink coupled to the exterior surface of the inverter housing, the heatsink including a second channel;
an inverter housing cover; and
a printed circuit board on an opposite side of the heatsink from the inverter housing cover;
wherein the first channel is defined by the inner wall of the inverter housing and the inverter housing cover,
wherein the first channel in the inverter housing and the second channel in the heatsink define a cooling circuit, and
wherein the first channel is fluidly connected to the second channel to pass a coolant through the cooling circuit.
