摘　　要：无刷起动发电机由双向变换器与同步电机构成,由于具有起动、发电双功能而成为机载电气技术研究的一个热点。该文研究基于两象限斩波器调压的无刷直流起动发电机系统的主电路拓扑与原理、起动机的起动特性以及发电机的调压特性与外特性,最后以实验室一台同步电机为例构成无刷直流起动发电机原理实验系统,实验结果表明该系统具有良好的起动、发电性能。Considerable attention has recently given to the brushless starter/generator(S/G), which is composed of a bi-directional converter and a synchronous machine, in the field of aircraft electrical technology, because of its double duty function of starting the aircraft engine and generating electrical power for aircraft. This paper is devoted to study the converter topology, operating principles, control characteristics of starting and generating operation of the S/G based on two-quadrant chopper PWM Control. Experimental results from a laboratory prototype are presented to validate the feasibility of the developed brushless DC S/G.
