Hi Sir,
I want to control 12V DC Fan using PWM. IRF540N MOSFET is used to drrive the DC Fan. DC Fan is what type of load is it inductive.which type of equivalent model can use either small signal or large signal model. what is the equivalent model for attached circuit.
how can i know operating point of the MOSFET, how to calculate the drain current. DC Fan is not running upto 60% duty cycle applied to the gate of MOSFET, WHY. how to know how much current the Fan wants to start and how much the MOSFET gives.
