One example is an inverter assembly for converting direct current (DC) to alternating current (AC). A DC connector on the inverter assembly is connected to an upper DC bus. A silicon carbide (SiC) heat sink is mounted above the upper DC bus and at least one capacitor is mounted above the SiC heat sink. A lower DC bus is connected to the upper DC bus and a liquid cooled cold-plate cooling unit is positioned between the upper and lower DC busses. SiC half-bridge units are located between the upper DC bus and the cold-plate and between the lower DC bus and the cold-plate. A gate driver unit is located on the upper DC bus above one converter heatsink and another driver located on the lower DC bus below the other converter heatsink. An AC output connector connects the converters to the AC output connecter.
