I am designing a 4-phase interleaved synchronous boost converter. Each phase has 2 MOSFET's which are not to be in conduction at the same time. I'm using STM32F407 discovery board. I am making use of TIM1 AND TIM8 channels to get complementary PWM's which ensures deadtime between two same-phase signals.
The problem is that I couldn't figure out a way to create a phase shift between the channels of TIM1. This would yield at least 2 pairs of pwm signals with their complementaries which are 90 degrees phase shifted and I could get other 2 pairs from TIM8. Creating the phase phase shift between two timers (like TIM1 and TIM2) is not an issue when using CNT registers.
I am not a very experienced user, comments and suggestions are very much appreciated, thanks!
