  "textContent": "A motor driving apparatus, a motor system, and an electric vehicle are described that 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 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 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.",
