I've written a program using Basic for SVPWM for PIC18F452. I'm told that there is a inbuilt deadtime (safe?) for these types of PIC's. However i want to implement some extra dead time in my program. How to provide it IN GENERAL? Can it be provided in the code itself?

P.S.- I will be driving an 3-phase Inverter using 2sk727 with it.

 

You will have to write code to turn on and off a pin (pins) yourself to do that. No adjustable dead time as far as I know. Check the DATASHEET on microchip.com. Very complete. If you need more, check the users guide to advanced 8-bit controllers.
