Comparative efficiency of switched reluctance and induction motor drives for slowly varying loads.

Abstract: A current-controlled switched reluctance motor drive for variable speed applications with efficiency optimization is presented. Firing angles are computed online, the turnon is calculated by means of the rule of Bose, and the turn-off is calculated using the general theory of the optimal turn-off angle proposed by Gribble. In steady state operation, the initial selection of firing angles is fine-tuned by means of an algorithm that minimizes the input power of the drive. An efficiency and electrical energy cons… Show more

“…An important step to increase the reliability of the HPC drive is to reduce the ripples of rotational speed of the rotor to a predetermined level when it is adjusted in the required range. Analysis of the research of the switched reluctance drive [8] shows that in steady-state modes, its efficiency decreases by 4 % with a double load reduction, which is confirmed by the results [9]. In this paper [9] the authors give the characteristics of the SRM with switch with C-reset and vibrational energy return for change in supply voltage and switching angles at a constant load.…”

“…Capítulo IV.-Control digital de motores de reluctancia autoconmutados utilizando un equipo para el desarrollo del control, modelado y prueba.En la tabla IV.4.5.1 y tabla IV.4.5.2 se puede observar la energía consumida por ciclo en el IM y la consumida en el SRM aplicando diferentes estrategias de control[AND06]. También se puede apreciar el consumo y el ahorro, que se produce, en ambos motores, si el ciclo se repitiese 10 veces al día durante 22 días al mes y considerando 11 meses al año.…”
