The invention provides an electric vehicle driving system, a controller and an electric vehicle. The electric vehicle driving system comprises at least one of a generator rectifying circuit and a motor driving circuit, and a power module. A bridge arm midpoint of a first bridge arm in the power module is used for connecting a power battery, and two ends of the first bridge arm are respectively used for connecting two ends of a bus capacitor. Two ends of three second bridge arms connected in parallel in the generator rectifying circuit are respectively used for connecting two ends of the bus capacitor, and bridge arm midpoints of the second bridge arms are respectively used for connecting a generator. Two ends of three third bridge arms connected in parallel in the motor driving circuit are respectively used for connecting two ends of the bus capacitor, and bridge arm midpoints of the third bridge arms are respectively used for connecting a driving motor. According to the application, the power module can reuse devices in the generator rectifying circuit or the motor driving circuit, the size of the electric vehicle driving system is reduced, the energy efficiency is improved, and the applicability is further improved.
