    Adding 6 IRFB4110 to a 72 Volt 20 Amp crystalyte controller

    The Power MOSFET IRFB4110 is rated for maximum VDS of 100 volts. In a 72 volt controller the main power rail can be as high as 84 volts when the battery is fully charged. As the MOSFET turns off the motor will generate an EMF from the magnetic field collapsing. This can be as high as 30% of the...
