Abstract

The invention relates to a direct-boosting doubly-fed switched reluctance generator current transformation system, which is composed of a storage battery, ten switch tubes, a three-phase winding, ninediodes, eight capacitors and two inductors, and is characterized in that the total output voltage is boosted directly under the condition of parallel connection of each phase output while the excitation and power generation of each phase winding, the problems of strengthened excitation and simultaneous work of two phase windings are solved at the same time, the switch tubes are not additionally increased, and the separated excitation storage battery can be automatically charged. Meanwhile, an automatic charging current transformation loop is utilized and can carry out backward feedback energyfeed after only fine adjustment, so that the cost performance and the adaptability are greatly improved, and the whole system is low in switching loss and high in output electric energy. The direct-boosting doubly-fed switched reluctance generator current transformation system is applicable to the field of low-power high-speed switched reluctance generator systems with various power inputs.

Description

technical field [0001] The invention relates to the field of switched reluctance motor systems, in particular to a switched reluctance generator transformer with direct parallel connection of high voltage output, enhanced excitation, automatic charging and reverse energy feedback, adapting to simultaneous operation of two-phase windings, low loss, and high power quality. flow system and its control method. Background technique [0002] As a new type of power generation system, the switched reluctance generator system has attracted more and more attention from the industry due to its advantages of low cost and high fault tolerance, but its converter system is the heart of its work, which greatly affects its value. , performance improvement, and its variable flow system has developed slowly over the years. [0003] Switched reluctance generators generally directly generate DC power, which often cannot meet the needs of load or grid connection in terms of voltage. Therefore, s...
