ABSTRACT:
A power conversion apparatus includes a plurality of power modules, a plurality of capacitors and a bus bar. Each of the power modules has a direct current terminal section and an alternating current terminal section. Each of the power modules is configured and arranged to convert a direct current inputted from the direct current terminal section into a respective phase of a multiple-phase alternating current and to output the multiple-phase alternating current to the alternating current terminal section. Each of the capacitors is arranged with respect to a corresponding one of the power modules. The bus bar forms an inter-phase current path between the power modules that are adjacent and forms an intra-phase current path between one of the power modules and a corresponding one of the capacitors such that an impedance of the inter-phase current path is smaller than an impedance of the intra-phase current path.
