Voltage sensor signal stability problem
Voltage sensor signal stability problem
(OP)
Dear All,
I am designing a voltage stablizier and had designed the circuit for it. However the voltage after LM324 IC is not a constant or stable value. It ramps up very slowly about 5 seconds and then sometimes go in the reverse direction. Ideally I would like it to ramp up ( if thats inevitable) quickly and stop on a steady value. Please see my circuit attached. The voltage sensor is the circuit beginning from 6v transformer
Many thanks in advance

The input to U5:A is a filtered rectified signal. It will contain some 100Hz (120Hz) ripple. Are you hoping to use this as a reference signal? Use a zener or a reference generator IC as the reference instead.
You are trying to use an inverting amplifier to produce a negative output voltage from a single-ended supply. It won't work.

If we learn from our mistakes I'm getting a great education!
