Abstract
A power conversion apparatus PWCS includes a smoothing capacitance element Cxp connected between a positive terminal and a negative terminal of a power source and configured to smooth a voltage change superimposed on a DC voltage, a switching circuit SWC converting the DC voltage into an AC voltage, a first bus bar BSBconfigured to electrically connect between the positive terminal of the power source and a terminal TCxof the smoothing capacitance element Cxp, a second bus bar BSBconfigured to electrically connect between the negative terminal of the power source and a terminal TCxof the smoothing capacitance element Cxp, and a filtering capacitance elements Cand Celectrically connected between the first bus bar BSBand the second bus bar BSB. The first bus bar BSBand the second bus bar BSBinclude opposing portions and are disposed to allow the current to flow through the opposing portions in the same direction.
