What is the purpose of a thyristor (SCR) in a half-wave controlled rectifier circuit?
A thyristor is to control the conduction of AC voltage, allowing only a portion of the input waveform to pass through and be rectified into DC. By adjusting the firing angle (the moment when the SCR is triggered to conduct), the SCR acts as a switch, regulating the output voltage and power delivered to the load. This controlled conduction of the SCR is vital for applications where variable DC voltage or power control is required, such as in lighting dimmers, motor speed control, and heating systems.
How to Calculate Average Output Voltage of Half Wave Controlled Rectifier with R Load?
