Beschreibung
Zusammenfassung:	A power converter, including: at least two inverting modules, where direct current sides of the at least two inverting modules are connected in parallel using a laminated busbar or a circuit board, and the at least two inverting modules run in an interleaved and parallel manner. In the present invention, the power converter is formed by connecting at least two inverting modules in parallel, and the direct current sides of the at least two inverting modules are connected in parallel using the laminated busbar or the circuit board, so that parasitic inductance between inverting modules is small, forming a low parasitic inductance loop. When the at least two inverting modules run in an interleaved and parallel manner, the low parasitic inductance loop counteracts most ripple currents in a circuit, thereby reducing the burden of the ripple currents on a bus capacitor. Therefore, the demand of the power converter provided in the present invention for the bus capacitor is small.
