I have an IRF 540 set up for PWM. Power source is 12v. battery The mosfet is being fed by a frequency generator at 20khz with varying duty cycle. The battery also supplies power to the frequency generator.
Can the mosfet be without a load during testing?
With the duty cycle I have set up I am measuring 1.6v (with a multimeter) from gate to ground.
Shouldn't it be 1.6v also from the drain to the positive side of the battery?
I'm getting 12v.
