A power conversion apparatus includes: a first capacitor branch, where the first capacitor branch includes at least one electrolytic capacitor, and is configured to perform voltage stabilization on a voltage received by the power conversion apparatus, to obtain a first voltage; a second capacitor branch, where the second capacitor branch includes a plurality of film capacitors connected in series, and is configured to: perform filtering on the first voltage, and perform voltage division on a first voltage obtained through filtering, to obtain a plurality of second voltages, where each film capacitor obtains one second voltage; and direct current converters in a one-to-one correspondence with the film capacitors, where an input end of each direct current converter is connected in parallel to the corresponding film capacitor; and the direct current converter is configured to perform voltage conversion on the second voltage output by the film capacitor.
