Abstract
A drive unit includes a substrate, a converter installed on the substrate, an inverter installed on the substrate, a P-side busbar, and an N-side busbar. The P-side busbar is a positive-side busbar connecting a P-side output terminal, which is a positive terminal of the converter, and a P-side input terminal, which is a positive terminal of the inverter. The N-side busbar is a negative-side busbar connecting an N-side output terminal, which is a negative terminal of the converter, and an N-side input terminal, which is a negative terminal of the inverter. Each of the P-side busbar and the N-side busbar is covered with an electrically insulating material. The P-side busbar and the N-side busbar are disposed in parallel with each other above the substrate.
