Hai,
I am trying to drive a separately excited motor using CSD19536KCS. My plan is to control , duty cycle of motor's armature using this circuit. Input frequency of PWM is 2.2KHz. The above mentioned MOSFET support above 120 Amps. My requirement is continuous 75 amps and 24 volt.
I already tested different MOSFET driver configuration and finally reached a circuit I attached herewith.
Here I controlled up to 30 amps, 12 volt continuously using single MOSFET. Heat is developed here but its ok.
Over that heat is developed tremendously.
When I am using 2 MOSFETs in parallel more noise is generated.
In most of the applications , there are more than one mosfets in parallel , even though the single one can handle the ratings.
What is the reason ? Is it for temperature handling?
