Industrial Power Control Using Integral Cycle Switching

Abstract

Implementing vital cycle switching, a method for controlling AC power by deleting particular AC signal cycles, cycles, or fractions of cycles, is the aim of this project.  In handling linear loads, such as electric oven heaters, this strategy has been widely used.  To achieve cycle theft of the voltage waveform in this project, an Arduino microcontroller is used. This enables exact control of the time-average voltage given to the load to generate triggering pulses on the Arduino; interrupts are triggered by zero crossing detection, which is done using a comparator. Following the usage of these pulses to drive optoisolators, which subsequently trigger the TRIAC for integral cycle control based on input switches interfaced to the microcontroller, these pulses are utilised to drive optoisolators.

A succession of loads should be used in place of a linear one. To check the output, a motor or bulb might be employed. It's vital to keep in mind that this method could lead to an imbalance in the input current or voltage waveform because of the on/off cycling across the load. While light is utilised in this project as a demonstrative tool, the main goal is to test whether the load turns on at the waveform's zero crossing even when switching occurs randomly. To deliver a controlled +5V DC supply for the microcontroller and other components, the project's power supply consists of a step-down transformer, bridge rectifier, capacitive filter, and voltage regulator 7805. To maintain the desired output to the load automatically during the appropriate cycle, a feedback mechanism can also be added.
