Power control for continuous duty ac electric motors using pulse width modulation

In current time, there are many expenses that average people pay for. One of which is their electric bill where people pay so much not just because they are using their appliances but because of the excessive consumption of the appliance itself. Continuous duty and intermittent duty rating Ac electric motors are demonstrated in the household through industrial floor fans, washing machine dryers and hair dryers and refrigerator respectively. The group utilized the concept of power control by the microcontroller function of Pulse Width Modulation (PWM) to control the work done by the AC electric motors, making a difference in power consumption. The design and construction of the system aims to reduce the power consumption of refrigerator compressor and continuous duty ac electric motors depending on the change in duty cycle with its corresponding voltage input
