Patent abstract

A compact inverter system includes a bus bar. The bus bar includes a terminal for connection to a positive terminal of a DC voltage supply. The compact inverter also includes a heat sink, a first transistor, and a second transistor. The first transistor has first and second terminals between which current is transmitted when the first transistor is activated, and a first gate terminal controlling the first transistor. The first terminal of the first transistor is thermally and electrically connected to the bus bar. The second transistor has first and second terminals between which current is transmitted when the second transistor is activated, and a second gate terminal controlling the second transistor. The first terminal of the second transistor is thermally and electrically connected to the heat sink. The first and second transistors are positioned between the bus bar and the heat sink. The first transistor is positioned between the second transistor and the bus bar. The second transistor is positioned between the first transistor and the heat sink.
