Hello,
I am trying to build a DC-DC converter that actually follows a linear path. When the input voltage is 6 Volts, the output should be 20 Volts and when I crank the input voltage to 10 Volts, I would like the output voltage to be 125 Volts.
I built a boost converter that worked for the 6v to 20 volt conversion. Then I thought I could just increase the duty ratio as I increased the voltage using a microcontroller. But even with a max duty ratio, I cannot get this to work.
My question is this: Is it even possible to accomplish what I am trying to do? I am building this for a class project. Thanks.
