Abstract
The invention relates to the switch reluctance generator whose main circuit is in parallel and series structure. The generator includes the stator, the rotor and the main circuit, which consists of the main switch and the flywheel diode. The characteristics are that the main circuit also uses the assistant diode to make up of the machine winding. The winding presents parallel connection in the excitation phase, but presents series connection in the power generation phase. Thus, the exciting voltage is increased at several times. The rate of growth of the exciting current is also increased. Strengthen energy storage of the motor field makes more mechanical energy transform to electrical energy so as increase the output power. Moreover, it enlarges the range of working rotate speed and lowers energy dissipation in the excitation phase so as to increase the efficiency.
