A novel high-efficiency parallel-winding connection for a three-phase induction motor fed by a single-phase power supply is presented in this paper. The proposed connection uses two sets of capacitors to achieve approximately symmetrical winding currents in the motor. A 2-D finite-element magnetodynamic model of the induction motor is presented. The Kriging surrogate model along with a global optimization method was used to find the optimal operating conditions of the proposed motor. Based on the conditions for the best efficiency at full load and the best starting torque of the motor, a straightforward calculation is proposed to select the capacitors. To demonstrate the validity of the proposed connection, experimental tests are performed in three induction motors. It is demonstrated that the rated load efficiency is the same and the starting torque is close when the motor is fed by a single-phase and three-phase power supply. Additionally, the rated power factor of the motor is near to unity. Our proposed motor connection has higher efficiency and higher power factor than a conventional single-phase motor.

“…On the other hand, if only single phase supply system is available, the single phase induction motors (SPIM) are the most common form in the lower horse-power ranges. So, the SPIM has been widely used in households as well as industry [1][2]. In addition, the SPIM has many advantages.…”

In the single phase induction motors, backward mmf causes torque and speed pulsations. This paper presents a new method to eliminate the instantaneous backward mmf to improve the performance of the single phase induction motor. In the proposed method a calculated reference current which is in quadrature with main winding current instantaneously, is injected to the auxiliary winding. The "Hilbert transformation" is used for obtaining the reference current of auxiliary winding by using the current of main winding. The proposed control scheme is simple and it does not need any position or speed encoder sensors. Basic system operation and theoretical analysis are discussed and simulation results in comparison with conventional method which uses sinusoidal voltage supply are presented to validate performance of the proposed method.Index Terms -single phase induction motor, main and auxiliary winding, instantaneous backward mmf, Hilbert Transformation, inverter.

“…Therefore, the method requires two sets of elements, one for the start-up period and the other one for the normal operation. In a slightly different approach proposed by reference [5], the optimum speed at which the switching of the elements should take place is predicted. References [6,7] propose an electronically interfaced capacitor whose effective capacitance may be varied by the duty cycle of an electronic switch.…”

“…The machine, however, may be connected to a single-phase power line, as the only available utility grid in most remote areas. Thus, this paper concentrates on the connection of the three-phase induction machine to a single-phase power supply.The subject matter has been extensively discussed in the literature [2][3][4][5][6][7], with the main goal having been to provide a balanced three-phase excitation for the stator windings of the machine.The most widely adopted voltage-balancing technique is to connect a capacitor, referred hereafter to as the voltage-balancing capacitor, across two of the stator terminals [2]. It can be shown that the most balanced three-phase voltage is achieved with a unique capacitance, referred (in [2]) to as the optimum capacitance.…”
