Abstract
Provided are a three-level power converter and a power unit thereof. The power unit includes a power switch module and a laminated busbar structure. The power switch module includes a first power semiconductor switch module and a clamping diode module, which have a first, second, and third terminal respectively. The laminated busbar structure includes a third, second, and first busbar layer laminated on the power switch module. The third busbar layer includes a first sub-busbar connecting to the first terminal of the first power semiconductor switch module, a second sub-busbar connecting to the third terminal of the first power semiconductor switch module and the first terminal of the clamping diode module, a third sub-busbar connecting to the second terminal of the clamping diode module and the third terminal of the second power semiconductor switch module, and a fourth sub-busbar connecting to the second terminal of the second power semiconductor switch module.
