A review on Variable Speed Control techniques for efficient control of Single-Phase Induction Motors: Evolution, classification, comparison

Abstract

Single-Phase Induction Motor (SPIM) is the main contributor to the electricity consumption in residential and commercial sectors where three-phase power supply is not available. SPIM efficiencies range from as low as 30% to as high as 65%, depending on the motor type and design. To guarantee the efficient use of energy, the investigation of different SPIM drives have been increased in recent decades. Efficient control policies of SPIM drives offer a great potential for energy saving. Thus research on optimum operation of SPIM drives is escalating. However, there seems to be an absence of a comprehensive review on Variable Speed Control (VSC) techniques for SPIM drives in order to address the need for a thorough insight on SPIMs’ drives. In this paper, the principal of control techniques for SPIM drives is explained and their pros and cons are discussed. Ultimately, from different perspectives, VSC techniques for SPIM drives are compared and appraised. It is envisaged that this paper will be a valuable one-stop source of information for researchers working in this topic.
