A power conversion apparatus, a charging pile, an on-board charger, and an electric vehicle are provided, to reduce operating costs of the power conversion apparatus and improve working stability of the power conversion apparatus. The 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.
