  "textContent": "A power conversion apparatus includes a filter capacitor to be charged with electric power fed from a main power source, and a power converter to convert electric power fed via the filter capacitor and feed the converted electric power to a load. The power conversion apparatus further includes a power-source contactor to electrically connect the filter capacitor and the power converter to the main power source or electrically disconnect the filter capacitor and the power converter from the main power source, and a discharging circuit connected in parallel to the filter capacitor. The power conversion apparatus also includes a discharge control circuit to close a discharging contactor included in the discharging circuit after opening of the power-source contactor, and thereby cause the filter capacitor to be discharged.",
