Hello,
I am busy with a project that boosts 12 V DC to 24 V DC through the use of a boost converter. I am only using 1 power supply - the 12 V DC. For the inductor to charge up and boost the voltage, a PWM is needed to switch a MOSFET so that is can do the boosting. So I have used a NE555 timer to do this successfully.
But at the moment my load to the converter is a constant 48 Ohm resistor, which gives 24 V output. My challenge is that I want to make the load vary. How can I use the timer to manipulate the duty cycle of the circuit to keep boosting at a constant 24 V, doesn't matter what the output resistance of the booster is?
