A Switched Reluctance Generator Converter System

Abstract

A switched reluctance generator conversion system, its structure is composed of two batteries, ten switch tubes, nine diodes, five capacitors, three-phase windings, two transformers, two batteries and three switch tubes can be high and low The excitation power supply with adjustable excitation output voltage in a low and wide range greatly improves the system adaptability and power generation capacity; directly relying on the simple conversion circuit of each phase winding, and with the support of the excitation power supply, it solves the problem that the output power generation voltage can be generated in a wide range The problem of adjusting the output, especially when the output is high voltage, saves the subsequent step-up link; for the two batteries that do not share the same ground in the excitation power supply, the present invention only uses one switch tube to realize the automatic isolation charging of the two batteries that do not share the same ground , improve the sustainability and reliability of the system, and simplify the structure and control; the invention is suitable for application in switched reluctance generator systems with various power inputs and various output loads.

Problems solved by technology

[0003] During the operation of the switched reluctance generator, before each phase winding sends out electric energy, it needs to absorb electric energy to store and excite its own winding. The excitation electric energy, especially the excitation voltage, greatly affects the excitation current of the phase winding and the output capacity of subsequent power generation. Therefore, The variable excitation voltage can be adjusted, especially to increase the adaptability of power generation output; on the other hand, the industry often uses battery packs as the excitation power supply, and the problem of battery charging occurs, especially when there are multiple batteries and they do not share the same ground. The charging system poses a challenge. If there are too many and too complicated charging systems, it will inevitably greatly increase the complexity of the structure and control of the entire system, as well as the cost, and reduce the reliability.
