Abstract :
A novel scheme using the operational amplifier to obtain voltage controlled time delay for triggering SCR´s is discussed. The variation of the delay with voltage is smooth and undistrurbed by stray pulses. The circuit is flexible and any desired relationship between control voltage and time delay can be obtained. This has wide application in solid-state power control.
