Abstract
This research aims to develop a new speed control method for a single-phase ac induction motor. It provides a low-cost, high-efficiency drive capable of supplying a PWM modulated sinusoidal voltage to a single-phase ac induction motor. An 8051-family microprocessor controls the circuit operation. The device is intended to replace the commonly used triac phase angle control drives. The circuit may power a single- phase alternating current induction motor (or a broader alternating current inductive/resistive load) with variable alternating current voltage. The voltage provided to the load, like in triac control, can be changed from zero to maximum value. It, on the other hand, employs a pulse width modulation (PWM) approach, which, when contrasted to the phase angle control utilized for triacs, yields.
