DSP based SRG load voltage control

The aim of this paper is to present a three-phase 6×4 switched reluctance generator load voltage control. The showed strategy uses a PI controller to vary the magnetization level of the phases during the magnetization period using a PWM signal. This strategy was simulated and than tested in a bench. Results of both simulations and experimental tests are presented here. It was used a low cost fixed-point DSP and a half-bridge converter. The results got showed that this strategy successfully controls the generated voltage applied to the load. Strategies for switched reluctance generator voltage control are important for vehicular applications.
