Industrial furnace power control by integral cycle switching without generating harmonics

Description

The outline of the Industrial furnace power control kit is integral Cycle switching, as a method to remove whole cycles, or portions of cycles of an AC signal is a well-known and old method of controlling AC power, especially across AC heater loads. However, the concept of achieving the cycle stealing of voltage waveform by use of microcontroller can be very precise as per the program written in assembly/ C language.

Industrial furnace power control is using the output we drive the optoisolator which acts as a switching element using this we will trigger the TRIAC on the base of TRIAC we can make the cycle stealing. Thus, the actual time-average voltage or current experience at the load is proportionately less than if the whole signal is applied to the load. Alternatively, the load is to be a single-phase series motor or lamp for speed control. One side effect of utilizing this scheme is an imbalance in the input current or voltage waveform as the cycles are switched on and off across the load.

• In this kit, we are using a comparator for zero-crossing detectors as an interrupt to the microcontroller.
• It is made of high-quality material which is more durable.
• Here the microcontroller gives the output on the base of the interrupt as the reference for generating the firing control.
