Increasing voltage from 0 -230 Volts over time

[Andy]

 

What I would like to do.

 

I am looking for a circuit that will increase the output voltage from 0 V – 230 over time ( 0 -3 secs, if possible variable).

 

Input voltage 230v Ac 20A max
Output voltage 0 -230v Ac 0 -20A

 

When a “switch/trigger” is present the voltage increases from 0 – 230v over the “set” time.

 

If at any time the “switch” is switched off, the voltage drops instantly to 0 V.

 

Therefore Slow rise, sharp off

 

The start signal will start the voltage rise and at some point the “stop” signal will be given (variable) and the process will stop, then repeat 1000’s of times continuously

 

The circuit will switch on/off every 3 seconds, or any point up to 3 seconds

 

Can anyone help

Hi Andy,

A low voltage version of that kind of signal is possible to generate using simple electronic devices like a charging capacitor, and to reflect that signal in a 230V supply you can use a power mosfet.
