What are the factors determining the PWM Frequency of the MOSFET driver circuit that drives a BLDC motor.
Is there any equation for PWM calculation?
For eg. I need to control the speed of a BLDC motor- (PMSM ME0201013001) with spec, 48 V, 5 kW (100 A continuous), 5000 rpm, 0.013 mH p-p inductance, 22 mOhm resistance.
Since my power electronic knowledge is not so strong, I need to ask, how does the MOSFET circuitry (two half bridges in each phases of BLDC) produce a Very High Current of 100 A in Motor Phases?
Circuit reference is from an evaluation board of ST Microelectronics.
I have seen some posts in Stack but that does not work out for me! (Sorry!!)
Thanks in advance
