A control method includes the following steps: when the DC-DC converter works every time, acquiring total time TC for controlling an H-bridge in a third mode and total time TD for controlling the H-bridge in a fourth mode, and acquiring set time Ti for controlling the H-bridge in the third mode and set time Tm for controlling the H-bridge in the fourth mode in each working cycle during a working process of the DC-DC converter; judging a relation between the TC and the TD; and selecting the mode for controlling the H-bridge when the DC-DC converter is started according to the relation between the total time TC and the total time TD, and alternately controlling the H-bridge according to the Ti and the Tm, the second switch tube, the third switch tube and the fourth switch tube in the H-bridge to be relatively balanced.
