Tanong ko lang mga masters ... Sorry for this unsound technique of electronics design via Trial and Error using simulators. Mga students huwag gagayahin! Trabahong tamad for someone who has very rusted basic electronics but its a quick jumpstart.
Question ko regarding the p-channel mosfet. In the figure, based on the measured voltage drop accross the mosfet, there is around 17V developed and around 1.5A going through it when triggered via a 1KHz 25% duty cycle PWM.
In actual ba, ganun din ang mamemesure ng tunay na DMM. What about actual power dissipation? Will there be an actual power dissipation of 17V x 1.5A accross the mosfet? The mosfet has an Rdson of around 100 milli ohm at 10V Vgs. It has a Vgsth of around 2~4V.
Lastly, I also noticed that increasing frequency w/o changing the duty cycle also increases the voltage developed accross the load resistor. Is this normal in actual circuits?
