The invention provides a voltage stabilization control method for a braking energy recovery power generation system of an electric vehicle, and belongs to the technical field of electric vehicle control. The braking energy recovery power generation system of the electric vehicle works under coordinative control of a reference circuit, a comparison circuit, a triggering circuit and an H bridge control circuit, and through control over the size and direction of power-on current of an electro-magnetic winding, the size of a combined magnetic field formed by an electro-magnetic field and a permanent magnetic field inside the air gap of a generator is changed, so that when the electric vehicle changes within a large braking speed range, output voltage is kept stable, and alternating current output by the generator is converted into direct current through a bridge type rectifier circuit and used for charging a storage battery or supplying power to electric equipment.
