The principle of the switched reluctance generator (SRG) based on the description of the electromagnetic characteristic, analysis of the phase current waveform, the energy conversion and other aspects, etc. are described, and the control schemes for modulating the power output of SRG, i.e. angle control, chopping current control, PWM control and excitation voltage control are introduced. Finally, experimental results of 6/4, 6/6, 8/8 SRGs are presented. Studies of SRG show that this novel generator can find a wide application field and has some superior characteristics of simple construction, high density of energy, high capacity of over loading, high fault tolerance performance, high performances of both steady and transient.
