Abstract

The invention relates to a switched reluctance generator current transformer topology and a control method thereof. The topology comprises an excitation power source, a main current transformer circuit, a bus capacitor, an isolated DC/DC converter and a discharging circuit, wherein the excitation power source supplies electric excitation for the main current transformer circuit. Through the main current transformer circuit structure and the control method thereof, the excitation effect can be enhanced, the charging circuit works when a storage cell of the excitation power source needs charging and enhancing power output capability and protection, power generation initial current capability is protected and properly enhanced through controlling the discharging circuit, whole system intelligence, high efficiency and high benefits are realized, a special excitation initiating power source is omitted, and the topology and the method are suitable for application in the small and medium switched reluctance generator current transformer field.

Description

technical field [0001] The invention relates to the field of switched reluctance motors, in particular to a converter circuit topology system of a switched reluctance generator and a control method thereof. Background technique [0002] The use of switched reluctance generators to generate electricity is a new type of electricity generation. [0003] The power generation conversion system of the switched reluctance generator is the foundation and key of the switched reluctance generator system, which is related to the efficiency, benefit and reliability of power generation. [0004] According to the working principle of the switched reluctance generator, its work is divided into two stages: excitation and power generation. First, the external power supply supplies power to the windings for excitation energy storage, and then under the action of the reverse torque of the operation, the magnetic energy storage is freewheeling and released, which is the output of power generati...
