  "textContent": "As a configuration to perform multilevel control of a voltage, the number of the components is decreased. A power conversion apparatus for a vehicle of an embodiment is provided with a single-phase two-level converter and a single-phase three-level converter. The single-phase two-level converter is composed of a capacitor, first to fourth controllable switching devices, diodes connected in antiparallel with the controllable switching devices, respectively. The single-phase three-level converter is composed of two series-connected capacitors, fifth to tenth controllable switching devices, diodes connected in antiparallel with the controllable switching devices, respectively. The single-phase two-level converter and the single-phase three-phase converter are connected in series at the AC input/output points. The single-phase two-level converter has smaller switching loss than the single-phase three-level converter, and the single-phase three-level converter has higher withstand voltage property than the single-phase two-level converter.",
