双绕组开关磁阻电机重复脉冲发电的解耦控制方法研究
Research on Decoupling Control Method for Repetitive Pulse Generation of Double Winding Switched Reluctance Generator
摘要
Abstract
In this paper,a switched reluctance pulse generator(SRPG)with double winding and its power converter topology are studied.The concept of energy ratio(ER)is proposed to measure the ratio of effective energy in the pulse output energy of SRPG system under repeated power generation operation.Increasing the ER value will enhance the system's efficiency,and power factor,and the analytical calculation formula of ER is derived based on the linear inductance model of SRPG.The results show that ER is not affected by the turn-on angles and decreases rapidly with the increase of the turn-off angles.Aiming at the instability problem of the traditional current chopper control applied to SRPG,an improved current single-tube chopper control strategy for SRPG is proposed.The results show that the control condition is decoupled from the control parameters of ER,and the pulse current can be controlled at the same time with high ER.The experimental results of single-phase 8/8 structure prototype verify the correctness of ER theory and the effectiveness of the proposed pulse current control strategy.关键词
