Abstract

Disclosed is a small-sized switched reluctance motor converter system. The system is composed of four alternating main circuits in two sets, an output circuit, a first subsidiary circuit and a secondsubsidiary circuit; the four main circuits alternately output direct current to the output circuit for direct rectify output, and the inversion link is omitted; the first subsidiary circuit can work in both directions, has the three main functions of charging a storage battery, strengthening the excitation and feeding energy backwards, and is flexible and adjustable; the second subsidiary circuitassists in achieving the three main functions and can achieve short-time double-fed power generation control work; a converter can be completely adopted as a motor during running; the system is simplein structure, diversified in function and suitable for complex four-quadrant running fields of small-sized speed-variable wind power, water pumping and energy storage power station integrated motor systems, integration micro-power grids and the like.

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...
