I am developing a peak current mode control of a H bridge dc converter. The output voltage of the converter is controlled by controlling the phase shift of leg B (Q3 & Q4). As it can be seen on the attached picture, the comparator is directly controlling the phase shift.
Since the comparator delivers 1 or 0 (On or Off state), I guess based on the On time I need to control the phase shift. What is the correlation (formula) of the On time vs phase shift?
