The invention discloses an electro-magnetic doubly salient motor driving and charging integrated system with energy feedback and a control method thereof. Four switch tubes Sa, Sb, Sc and Sd are added in a front-stage bidirectional DC/DC converter of a two-stage converter topology of the system, and an energy feedback path in a system driving operation mode is formed by combining a split excitation winding; when the electro-magnetic doubly salient motor is braked and runs, the braking energy can be fed back to the storage battery side under the condition that the excitation current direction is not changed in combination with the control of the energy feedback path, the energy utilization rate and the performance of the driving system are improved, the parallel control of the two sections of split excitation windings can be realized in a charging working mode, and the high-power charging requirement of the storage battery is met.
