  "textContent": "This application provides a motor driving apparatus, a motor system, and an electric vehicle, to improve running efficiency of a motor and avoid damaging an inverter. The motor driving apparatus includes a three-level inverter, a motor parameter obtaining circuit, and a control circuit. The three-level inverter is configured to be separately connected to a first power supply and a motor, to invert a direct current provided by the first power supply into an alternating current, and provide the alternating current for the motor; the motor parameter obtaining circuit is configured to be separately coupled to the motor and the control circuit, and is configured to: obtain a motor working condition signal of the motor, and provide the motor working condition signal for the control circuit; and the control circuit is configured to: select a target working mode from a plurality of working modes based on the motor working condition signal, and control the three-level inverter in the target working mode, so that a midpoint voltage of the three-level inverter is less than a first voltage threshold.",
