Abstract - The proposed research seeks to implement integral cycle switching for the regulation of ac power in linear loads such as electric furnace heaters. Integral cycle switching generally involves eliminating the entirety of a cycle or certain cycles from an AC signal. At328 family devices programmed in assembly/C language are used to achieve this, ensuring that the real-time average voltage at the load is proportionately lower than the total signal whenever the signal is applied to the load. For zero-crossing detection, a comparator is employed, and an interrupt is sent from it to the AT 328. Hence, the AT 328 generates triggering pulses and output in accordance with the interrupt that was received.
The integral cycle is therefore accomplished in accordance with the input switches interfaced to the AT 328. Instead of using a motor, a lamp is used to check the output. Yet, the idea of using an Arduino to cycle-switch the voltage waveform may be executed with great precision thanks to a software written in assembly language, resulting in a time- average voltage or current at the load that is proportionately less than the total signal sent to the load. To validate the output, a series motor or lamp can be utilized in place of the linear load that will be employed in the output. When using this method, the input current or voltage waveform may become unbalanced when the cycles are cycled on and off throughout the load. For zero crossing detection in this project, a comparator is used, and the output is delivered as an interrupt to an Arduino processor.
Key Words: discontinuous-phase control, integral-cycle control, speed control, single-phase induction motors.
