I need a mosfet that can switch about 800 W , 100V and I want to switch by PWM that its frequency is about 40 KHZ.
What kind of mosfet Could I use? Is the "FQP10N60C" good for this?
I want to make a Drive for a BLDC Motor.
Thank you.
100V inductive load? resistive load? What is the max inrush current?
Why 40kHz - that's pretty high for this kind of voltage/power level and it going to make EMI issues harder
to tame. The choice of MOSFET is best found by parametric search given the desired specs.
IGBTs are worth considering at this voltage, more robust to large delta-V, although the losses will
probably be higher, and they are usually 600V rating or above so you don't have to worry about
over-voltage spikes or ringing taking them out.
