According to the present invention, a driving circuit of a hybrid vehicle comprises: a first battery and a second battery; an inverter converting an applied voltage into DC or AC in accordance to an operation mode of a motor; a converter operating in a pressure rising mode or a pressure decreasing mode in accordance to the operation mode of the motor; and a processor controlling an electrical connection of the first battery, the inverter, and the converter by comparing the voltage (V_B1) of the first battery and the voltage of a DC-link capacitor in an initial driving. The DC-link capacitor is a capacitor connected in parallel to the first battery, the inverter, and the converter.
