摘要： A power converter includes a PCB (1) having opposing first and second sides (11, 12), and a plurality of first commutation units and first capacitor unit disposed on the PCB. Each first commutation unit includes first and second discrete component (Q1, Q2). The second end of the first discrete component (Q1) is electrically coupled to the first end of the second discrete component (Q2), and the first capacitor unit (Ca) is electrically coupled to the first ends of the first discrete components (Q1) and the second ends of the second discrete components (Q2) in the plurality of first commutation units, respectively. The first and second discrete components (Q1, Q2) in the plurality of first commutation units are arranged in a row. The first and second discrete components (Q1, Q2) in each first commutation unit form a commutation loop together with the first capacitor unit (Ca).
