Provided herein are power converter of a drive unit for an electric vehicle. The power converter includes an inverter having a first transistor, a second transistor, and a capacitor, and a laminated bus-bar having a positive bus-bar segment, a negative bus-bar segment and a phase bus-bar segment. The positive bus-bar segment, the negative bus-bar segment, and the phase bus-bar segment can be disposed about the capacitor to form a lead frame coupled with the capacitor. The lead frame can include a first lead coupled with the first transistor. The first lead can include portions of the positive bus-bar segment and the phase bus-bar segment. The lead frame can include a second lead coupled with the second transistor. The second lead can include portions of the negative bus-bar segment and the phase bus-bar segment.
