The invention discloses a novel double-stator switched reluctance motor integrated charging function driving converter. The converter comprises a novel modularized U-shaped double-stator switched reluctance motor inner and outer stator windings, two rectifier direct-current bus capacitors, an electric vehicle storage battery, a first relay, a second relay, and two sets, each set comprises six switch tubes and six diodes, and each switch tube and diode set and the bus capacitor form a power converter for driving inner and outer stator windings of the double-stator switched reluctance motor. Bus current is provided by a rectifier connected with an alternating current power grid, and opening and closing of the inner and outer stator power converters are controlled through opening and closing of the first relay. During disconnection, the inner stator works in a power generation state by driving the outer stator to realize isolated charging, and the working mode of the electric vehicle is changed by controlling the opening and closing of the second relay to realize non-isolated charging. The internal and external stator structures and the electrical isolation characteristics of the novel sectional type double-stator switched reluctance motor are utilized, the motor winding and the existing power switch device are utilized to form the integrated driving converter with isolated and non-isolated charging functions, use of power switch tubes is reduced, the cost of the electric vehicle is reduced, the driving and charging functions are fused, and meanwhile, the safety is enhanced.
