I am doing an Op Amp voltage regulation of voltage drop across load. As you can see from diagram, I have a fluctuating_Vin (0V to 50V) and I want the voltage drop at load (100 Ohms) to be the same (14V) at all times no matter whether input voltage is 20V or 30V or 50V?
Note: I believe that the voltage drop across load can be controlled by changing duty cycle inputed into the transistor. The change in the V_in of op-amp will change the duty cycle which in turns affect the voltage drop of load. How to relate both of this together in a circuit ?
Question: Is there a way to regulate the voltage drop at load?
Thank you for reading . Have a nice day
