Abstract :
This letter systematically investigates and compares the performance characteristics of a variable-speed capacitor-run induction motor driving a domestic fan load using an ac voltage regulator and a single pulsewidth-modulated (SPWM) ac chopper. This proposal is a significant break from the conventional conclusion since it is shown that the SPWM ac chopper is inferior to the phase angle control scheme for a capacitor-run motor load.
