PWM Deadband
Posted: Tue Dec 16, 2014 8:53 pm
I have a design to drive 4 output transistors configured in an "H" bridge arrangement. Switching these transistors is not trivial since turning ON the transistors needs to be delayed to allow the other transistors to turn off fully. This prevents short duration current pulses that can damage the transistors.
The PIC chip PWM [pic18f4525], I believe, has a variable that can take care of this but I don't see any reference to it for FC5.
Can you give me feedback on this subject? - I have resolved the switching delays using hardware but would like to know if there are plans for the crossover switch deadband if FC?
Thanks
