Hoping you guy's can give me some ideas.
I am building a sysyem that will drive multiple, 3300V/1500A IGBT's.
The driver circuit has a Fiber Optic input for the Gate drive, and a Fiber Optic output for the status and fault information.
The status information is a 700ns pulse, and any longer than 1.5usec means a fault condition.
The driver was designed to interface to a controller, but my design is discrete logic.
I don't care about the status pulses, only the fault conditions, so I need a circuit that
will ignore the 700ns pulses.
Using a Microcontroller is out of the question for this design. The system will be generating pulses of up to 3.5MW, so it is not an environment where I can trust a microntroller.
Anybody got any ideas?
