Problems solved by technology

[0003] For the current conversion systems of various types of switched reluctance generators, the conversion mode and the conversion circuit of each phase winding of a switched reluctance generator are the same, and the conversion control mode of each phase winding is also the same, but In some demanding occasions, the control mode is complicated, so the windings of each phase adopt the same structure and control, so the overall control complexity is caused, and the switching loss is also large.
[0004] Moreover, in the current conversion mode of each phase winding of the existing switched reluctance generator, the work of each phase winding is independent and does not interfere with each other, and the respective work is carried out according to the rotor position information, so that the respective conversion circuits are also relative. They are independent and do not use each other. If it is necessary to strengthen the excitation, it must come from a special external excitation power supply. Even if a certain phase winding is in the stage of strong power generation, its electric energy will not directly participate in the strengthening of the excitation of the other phase winding, so the system is split , the benefit cannot be maximized

Abstract

The invention relates to a high-speed direct current switch reluctance generator converter system. The system comprises four-phase windings, six switch tubes, seven diodes, five capacitors, an inductor and an isolation converter. Converter loops of the first phase winding and the second phase winding have simple structures and the same control modes, and a third phase winding and a fourth phase winding are asymmetrically integrated conversion structures. By depending on the relatively complex converter loops and the regulation and control of the fourth phase winding, the measure of enhancementof the power generation capacity of the fourth phase winding itself can be achieve such as a follow current stage, and the fourth phase winding can be mutually promoted with the third phase winding to indirectly improve the power generation capacity of the first phase winding and the second phase winding; and besides, the structure is high in expandability, the output end is connected in series to increase the voltage, the total excitation source of each phase winding is regulated according to the duty ratio of a sixth switch tube so that the high-speed direct current switch reluctance generator converter system is a set of high-performance conversion system, is especially suitable for the high-speed direct current switch reluctance generator application field, and can be taken as one ofthe generator in the internal direct current microgrid in a full-electric aircraft.
