The flying capacitor three-level DC-DC converter comprises: an inductor, a first switch tube, a second switch tube, a first diode, a second diode, a third diode, a flying capacitor and a controller. When the difference between the voltage of a direct-current bus and the voltage of the flying capacitor is greater than or equal to the withstand voltage of the second diode, the controller controls the DC-DC converter not to operate, so as to reduce the voltage of the direct-current bus. When the voltage of the direct-current bus is extra high or a pre-charge voltage of the flying capacitor is extra low, the DC-DC converter operates, and thus the second diode bears an extra-high voltage and is easily damaged. Therefore, by means of reducing the voltage of the direct-current bus, the voltage of the flying capacitor Cf is synchronously raised by means of charging until the difference between the voltage of the direct-current bus and the voltage of the flying capacitor is less than the withstand voltage of the second diode, and then the DC-DC converter operates, such that the safety of the second diode can be ensured.
