here is a modified version of the variac code, with a slow start and slow stop function. It takes about 2.5 seconds to ramp up to the set point when pin D8 is pulled high. And when D8 is pulled low, slow stop will execute taking the output gradually down to zero.

I thought you might find this useful in your development of the inverter electronic control loop.


Thanks a heap Poida I'm currently snowed under with preliminary new house stuff but will be back onto it in a week or so.

Is it just a slight change to the pin definitions to change the Vadjust to be on the same as the Vfb sense pin of the nano-verter, without breaking anything ?  It will be easier to hack my current board if this change is ok.
If at first you dont succeed, I suggest you avoid sky diving....
