Abstract
A dualistic power set of an electric motor car comprises a generating set, a controllable rectifying bridge, a controllable charging part, a super capacitor bank, a wave chopper and a controller, wherein, the power supply output end of an AC generating set is connected with the controllable rectifying bridge and the controllable charging part; the DC power supply output end of the controllable charging part is connected with the anode of the super capacitor bank; the anode of the super capacitor bank is connected with the output anode of the controllable rectifying bridge through a diode, and is connected with the motor armature of an electric motor car through the wave chopper. During normal running of the electric motor car, an internal combustion AC generator set which is assembled by the electric motor car provides power to the electric motor car; moreover, if surplus electric energy is left, the super capacitor bank can be charged. When an electric motor is in braking state, the super capacitor bank is charged to store energy; therefore, in case that the electric motor car speeds up to overtake another car or goes uphill, the AC generating set and the super capacitor bank provides power to the electric motor car together, i.e. the super capacitor bank releases electric energy to compensate the impact electric energy needed by the electric motor car.
