I want to implement a hard switched full bridge converter with peak current mode control on STM32.
I thought of using the STM32 peak current control block. Is it somehow possible to implement the needed fixed phase shift of 0.5 for driving the diagonal mosfet pairs alternating?
The HRTIM in the PCC can not be configured with phase shift, neither can the HRTIM in the PCC block be controlled by a HRTIM Master (I thought of using two PCC blocks with phase shift of 0.5).
Is there a solution for this problem?
The peak current controller in the STM32 TSP can’t provide phase shifted PWM signals to the two legs of the full bridge. The only component in the STM32 TSP which can provide phase shifted PWM signals is the HRTIM block. However, as the STM32 TSP doesn’t provide an Analog Comparator block, I don’t see a way to build a peak current controller for a full bridge converter using discrete blocks.
The TI C2000 TSP provides a wider range of functionality than the STM32 TSP because we have been developing it for a longer time. Is there a chance that you could build your application using a TI microcontroller?
