Controlling VFD using arduino - 0-10V PWM Output

Hi,

I am looking to control a variable frequency drive using my arduino uno. It was initially controlled using a 10k potentiometer. How would I go about connecting the 3 potentiometer wires to the arduino such that it is able to output 0-10V on command. I currently have a RC circuit design that outputs 0-5V....

To get a 0 to 10V you will need a DC-DC converter, you should look it up but basically it's a transistor that switches on and off (with your PWM as input) so you can actually control the 10 volts using your 5V arduino output
