Independent Dead-time for Advanced Timer

Hi All,

 

I'm using the advanced timer TIM1 on STM32303VC to drive a 2 phase shifted full bridges separated by a transformer (Dual Active Bridge topology). This required use of 4 PWMs. CH1 and CH1N drive the primary bridge. CH3 and CH3N drive the secondary bridge.

The question is I need to program independent dead times (for CH1-CH1N and CH3-CH3N). Is that possible? Because the LL APIs have only one dead time configuration value per Timer.

 

If it's not possible what is the workaround? This is a make or break situation for my converter.

 

Regards,

Vivek
