Abstract
An integrated inverter assembly including a main cover and an opposing back cover, a coolant channel separating body interposed between an upper coolant channel and a lower coolant channel. The upper coolant channel may be thermally coupled to a first plurality of electronic components of the integrated inverter assembly. The lower coolant channel may be thermally coupled to a second plurality of electronic components of the integrated inverter assembly. The first plurality of electronic components include at least one gate driver.
