How To Increase the Input of an AC Power Supply every second

[jamiexx]

Hi There, I'm currently working developing a bench test, in one phase of the test I need to increase the value of the Voltage till the value of Current is equal to 6A, any idea how I can do it, at the moment I'm using a shift register to increase the value of input but not working.

Show us the code.  You also need to be adding to the voltage until you reach your desired current.

I was thinking to upload the code but I think is useless because the drivers of the AC supplier and the Wattmeter, the first part is the initialization of the AC supply the second part is where I'm trying to increase the Voltage per 1v each second without success, the output is measured with a Wattmeter that I already can control

Why aren't you setting the voltage inside of your loop?

Thanks haven't tried that, I will try and will go back, thanks

UPDATE 1.0

thanks for the idea, now the voltage is increasing but when I check the output nothing goes out, may I ask, the ''output driver'' should be out of the loop or inside?,

Update 1: Voltage inside loop

Update2: Now the Value is updated every second but thee output is not working

btw: I check everything and there's no problem with AC supply, the code is not working atm

Update2.0

Thanks for the tip, now I can control everything, I found the solution for the output of the Voltage, again thanks you so much

Warm Regards
