I have a couple of questions regarding current mode control. In peak current mode control, there is need for slope current compensation to avoid subharmonic instability. There is a lot of confusing, complicated literatrure to show why this is needed, but how do we calculate the slope amplitude to add to the sensed current?
Furthermore, does average current mode still use a peak current mode controller, but just the current reference is replaced with the output voltage reference point? Or is the circuitry for average current mode completely different to that of the peak current mode controller?
Thanks!
