Problems solved by technology

[0005] When the switched reluctance generator is running, the existing converter system, in the excitation stage, many excitation power sources have realized the self-excitation mode, so that there is no need for manual work of frequent battery replacement or charging in the separate excitation mode, but many existing self-excitation The mode is selected to increase the excitation circuit to directly provide the excitation power, but when the generator starts, a separate battery branch is required to provide the starting excitation power, which increases the structural complexity

Abstract

A small switched reluctance motor converter system, consisting of two sets of four main circuits, output circuits, first sub-circuits, and second sub-circuits alternately, the four main circuits alternately and directly output alternating current to the output circuit for direct rectification output , eliminating the inverter link, the first sub-circuit can work in both directions, and has three functions of charging the battery, strengthening excitation, and reverse energy feedback, which are flexible and adjustable. The second sub-circuit assists in realizing the above three functions and can realize short-term The converter of the present invention can be fully used when operating as a motor; the system structure is simple and multifunctional, and is suitable for complex, four-quadrant operations such as small-scale variable-speed wind power, integrated motor systems of pumped storage power stations, and integration into microgrids field.

Description

technical field [0001] The invention relates to the field of switched reluctance motors, in particular to a low-power intelligent multifunctional switched reluctance motor converter structure and a control method thereof. Background technique [0002] The structure of the switched reluctance motor is simple and strong, there is no winding on the rotor, no permanent magnet, the heat dissipation pressure is small, the reliability is high, and the manufacturing cost is low. The failure of one phase winding does not affect the normal operation of the other phase windings. It has strong fault tolerance and broad application potential. application prospects. [0003] Switched reluctance motors generally have multiple phase windings symmetrically distributed on the salient poles of the stator. The phase windings that are energized are determined according to the relative positions of the salient poles and grooves between the stator and rotor. Work; when working as a generator, eac...
