Question

Ac power in a load can be controlled by connecting

Answer 1

AC power control with thyristor using pic microcontroller is designed to control AC power flow across load. This project is designed using PIC16F877A microcontroller and Zero crossing detection circuit. Phase angle control method is used for AC power control with thyristor. Thyristor is used as a switch to control flow of power. PIC16F877A microcontroller is used to detect zero crossing and to generate pulse signals at a specific angle for thyristor. It is used in many power electronics project. Many final year electrical projects are based on this ac power control.

Answer 2

The Ac power can be controlled in a load by connecting the Silicon Controlled Rectifier System in a parallel arrangement.

The Silicon Controlled Rectifier has the function to keep the normal current into limits so that the power being traveled as load can be all through controlled.

It is to be placed in parallel arrangement so that the triggering of the Silicon Controlled Rectifier be efficient in every cycle of AC circuit.
