Abstract
This chapter presents the working principle and modeling of the single-phase induction motor (SPIM), as well as the control strategies of the SPIM with several different power electronics device-based variable frequency AC drives. The SPIM has been widely used for the water pumps, compressors, and fans with no tough demand for high performance and they are especially used at small-rated power below 1kW. Besides the conventional single-phase main power supply, the SPIM can also be supplied by a single-phase or three-phase voltage source inverter. This chapter will first introduce the working principle of the SPIM, and then establish the modeling of the motor. Thereafter, this chapter will present theoretical analysis on how the SPIM performance is influenced by different supply methods, i.e., including the supply methods using a single-phase inverter with a running capacitor, or using a three-phase inverter with/without a running capacitor. Further comparisons will be made in terms of starting torque, starting current, pulsation torque, efficiency, etc. Simulation results are provided to compare and demonstrate the similarities and differences between these power electronics device-based variable frequency AC drives for SPIM.
