Abstract

A four-phase switch reluctance motor power converter is composed of eight switch tubes, four diodes, two capacitors, a storage battery, an inductor and an isolation bidirectional DC / DC. Every two adjacent windings in a main circuit form one group; when the main circuit completes magnetic excitation and power generation, the output voltage value can be increased; the magnetic excitation storage battery can be charged according to needs and meanwhile can feed energy backwards; one power converter is adopted when a motor runs; the power converter is simple in structure, convenient to control, lowin switch tube switching frequency, low in loss, high in flexibility and adaptability and suitable for various power generation / electric occasions.

Description

technical field

[0001] The invention relates to the field of switched reluctance motors, in particular to a high-performance power conversion system of a four-phase winding switched reluctance motor and a control method thereof. Background technique

[0002] The switched reluctance motor has a simple and solid structure, low manufacturing cost, no windings on the rotor, no permanent magnets, high reliability, and the failure of one phase winding does not affect the normal operation of the other phase windings. It has strong fault tolerance and has broad application prospects.

[0003] When the switched reluctance motor is used as a wind power generator, it has the advantages of low cost and high reliability compared with double-fed asynchronous or permanent magnet synchronous wind power generators; as a motor in various industries, its excellent body structure and operating characteristics are also have considerable advantages.

[0004] Switched reluctance motors generally ...
