I would like to add an AC signal with a DC signal to create a power supply (DC+/-||AC||)
- AC signal - variable frequency from 1Hz to 1MHz Sine-wave. VAC = 500mV p-p, IAC = 1A p-p
- DC signal - variable voltage from 1V to 4V, current is 15A.
Purpose AC signal can run on top (superimpose) of the DC signal.
The problems:
- If I am using a regulator (which I never has experience with) at the output, then it might cut-off the AC. If I do not use a regulator, the the output might not be stable.
- I research how to superimpose this by using a high current op-ams (up to 20A DC) but it is very expensive around $300 on Digit Key.
How can I overcome these two 2 problems?
