The invention discloses a SiC power device driving circuit capable of suppressing bridge arm crosstalk and a control method thereof. The driving circuit comprises a G-pole driving circuit, an S-pole driving circuit and a capacitor arranged between the G-pole driving circuit and the S-pole driving circuit. The G-pole drive circuit comprises a positive voltage power supply, a first G-pole switch tube, a second G-pole switch tube, a switch-on resistor and a switch-off resistor, wherein the first G-pole switch tube, the second G-pole switch tube, the switch-on resistor, the switch-off resistor andthe second G-pole switch tube are used for controlling the G-pole voltage state and are sequentially connected in series. The S-pole drive circuit comprises a negative voltage power supply, a first S-pole switch tube and a second S-pole switch tube, wherein the first S-pole switch tube and the second S-pole switch tube control the S-pole voltage state. The negative-voltage power supply, the firstS-pole switch tube and the second S-pole switch tube are sequentially connected in series. According to the invention, the influence of the gate-source parallel capacitor on the switching speed is reduced, and the problem of bridge arm crosstalk is effectively inhibited.
