UJT Relaxation Oscillator, circuit and Applications: An oscillator is a device that produces a waveform by its own, without any input. Though some dc voltage is applied for the device to work, it will not produce any waveform as input.…
Ramp and Pedestal Triggering Circuit Diagram The circuit for ramp and pedestal triggering of two SCR’s connected in antiparallel for controlling power in an AC load. This circuit, R acts as a potential divider. Wiper (pot) R controls the value of pedestal…
UJT Triggering Circuit The supply voltage of the secondary winding of transformer is rectified by the half wave rectifier diodes and given to the zener diode. The zener diode is used to clip the rectified to a fixed voltage This voltage is applied…
