  "textContent": "The present disclosure provides a multi-input power converter, including three bridge arm units connected between a three-phase alternating current power supply and a positive/negative direct current bus. A first capacitor and a second capacitor are connected in series between the positive direct current bus and the negative direct current bus, and a node formed by connecting the capacitors is connected to a neutral point. Each bridge arm unit includes an inductor and a bidirectional switch unit that are connected in series, and a current direction control bridge arm connected between the positive direct current bus and the negative direct current bus, and a node formed by connecting the inductor to the bidirectional switch unit is connected to the current direction control bridge arm. Second ends of bidirectional switch units of the three bridge arm units are connected to the neutral point. In a battery mode, two of the bridge arm units are used as battery mounting bridge arms to constitute a direct current loop with a rechargeable battery, to supply power to the positive direct current bus and the negative direct current bus, and the remaining bridge arm unit enables an inductor on the bridge arm unit to alternately connect the positive direct current bus and the negative direct current bus, to balance a bus capacitance voltage. The power converter has high conversion quality, a small quantity of elements, and a reduced volume.",
