摘要
根据开关磁阻电机发电运行时相电流波形变化特点,该文提出了一种新颖的全导通斩波发电控制策略。该控制策略不需增加任何外围信号检测电路即可实现无位置发电运行,通过理论分析、仿真计算论证了方案的可行性,并在一台6kW 6/4结构的发电机得到成功应用。试验结果表明除效率略有降低外,全导通斩波控制的SRG具有控制简单、可靠性高等优点,因此采用全导通电流斩波控制模式的SRG具有良好的应用前景。
A novel current chopping strategy for switched reluctance generator(SRG) -a full conducted currentchopping(FCCC) scheme is presented in this paper. According to characteristics of phase current wave of SRG generatingoperation, it can generate under sensorless condition withoutadditional circuit or position signal algorithm. Simulation isdemonstrated the feasibility of this scheme in detail. Theexperimental results of a 6kW 6/4 configuration SRG show its simplicity and high reliability with little decrease in efficiency. So the SRG with FCCC will be used widely.
