hi,
i am facing h-bridge problem with high voltage. i am using 2 PNP and 4 NPN transistor.
PNP: TIP127, and NPN: TIP122
i got problems in calculating the resistor value before the base to control the current flow rate.
that is the value that i should use?
another problem here is, the BJT gets heated up badly when i supply 80V.
the spec of the motor is 80v, 2.778A.
the optocoupler(4n35 is for controlling the speed of the motor and the direction)
need help and advice urgently, thanks for helping
