Power module and inverter module design to minimize parasitic inductance and optimize thermal performance

A leg of a power converter, the leg comprising:

• a first one of (a) a first power module and (b) a first die, the first one including a high side switch having a first terminal configured to be connected to a first direct current (DC) busbar having a first potential;
• a second one of (a) a second power module and (b) a second die, the second one including a low side switch having a first terminal configured to be connected to a second DC busbar having a second potential that is different than the first potential;
• an alternating current (AC) busbar disposed vertically (a) between the first one and the second one and (b) between the first DC busbar and the second DC busbar;
• a first heat sink that is configured to draw heat away from the first one;
• and
• a second heat sink configured to draw heat away from the second one,
• wherein the AC busbar includes:
• a first electrically conductive portion that is disposed vertically above a first vertically upper surface of the first one;
• a second electrically conductive portion that is disposed vertically below a second vertically lower surface of the second one;
• and
• a third electrically conductive portion that is electrically connected to the first and second electrically conductive portions.
