Hybridization of a Single-Phase Induction Motor

Energy saving has been a challenge for decades. The conventional solution to this problem has been to manage it at the generation or distribution end. In any household, there is always some power lost during the conversion from AC to DC and vice versa. Therefore, rather than trying to increase conversion efficiency to address this problem, with this project sought to eliminate the conversion process. The concept of a DC home, in which PV panels feed DC power to homes directly is becoming increasingly popular. However, this DC power further undergoes a conversion to AC before being supplied to any household appliance. If the load is DC, this AC power is again converter to DC through a front-end rectifier built in the appliance. An increasing number of appliances are of DC loads today; phones, laptops, TVs, gadgets, light bulbs, etc. This leads to a lot of conversion losses in operating a conventional single-phase induction motor. Therefore, the goal of this research is to hybridize i.e., to enable a SPIM to operate on both AC and DC power, allow the SPIM to be self-starting and control the motor speed using V/f control.
