Dead band not in snyc

[Dipak_95]

Dear Team,

I am using the STM32F103C8T6 MCU and I am trying to generate PWM signals with dead band.

and according to my configuration dead band is not in sync.

Please let me know what configuration I have to make?

Note: I have gate driver which Lin is INVERTED so, that's why I am generating this type of PWM [ you can say complimentary ]

[ I have attach the c file ]

Best and regards,

Dipak

Hi,

you have to set OCx and OCxN complimentary, then you get deadtime on every rising output.

If both active hi , you get, what you see on your pic :

So its for driver with both inputs active hi , not mixed hi/lo.

Use a inverter on the active lo driver input - or other driver.
