Single power converter system of separately-excited high-gain switch reluctance machine

Abstract

The invention relates to a single power converter system of a separately-excited high-gain switch reluctance machine. Each phase winding is provided with a switch tube and a diode, and the single power converter system is simple in structure and is convenient to control; with the introduction of a transformer, the function of high voltage gain and isolation are helped to be achieved; and except that working condition running of a power generation at two stages of excitation and power generation is simply completed by the power converter, the same control mode can be used as working condition control running of a motor, and the single power converter system is applicable to occasions of various small-power switch reluctance machines / motors.

Description

technical field

[0001] The invention relates to the field of switched reluctance motors, in particular to a simple-structure power converter and a control method for a separately excited high-gain voltage switched reluctance motor. 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 gene...
