Кто может - поясните пожалуйста, почему нельзя использовать current-mode control, если первичная обмотка развязана конденсаторами? О каком конфликте идет речь?
Нашел ответ в - However, this technique is not applicable to the half-bridge topology because of the soft center-point voltage of the half-bridge capacitor divider. Any on-time imbalance—which is inherent in peak current-mode control—will result in the center point drifting towards either the ground or the input voltage. And peak current-mode control merely reinforces this trend which leads to unregulated output voltage and, possibly, transformer saturation. In 

voltage-mode control of the half-bridge topology, if one phase is on longer—whether due to device or timing mismatch—then the voltage applied to the transformer is lower because the capacitors are on longer and are discharged further. The volt-second product applied to the transformer from one phase to another is thus balanced. The drift of the center point of the capacitor divider acts as a negative feedback, avoiding transformer saturation.
