I am developing a dual active bridge converter, which is very similar in operation to a phase shift full bridge converter. I am implementing peak current mode control using comparator 2.
In the plot below, Channel 3 (magenta trace) is the comparator output, and Channel 4 (green trace) is the current feedback / comparator input.
Note that the rising edge of the comparator triggers at approximately 3.02 Volts, and the falling edge releases at approximately 720mV. I would expect the edges to rise and fall at about the same magnitude, with the hysteresis. Can somebody please explain this behavior?
Thanks in advance for any assistance.
