Peak current modePrimary side detectionA new cycle-by-cycle control flyback converter with primary side detection and peak current mode control is proposed and its dynamic characteristics are analyzed. The flyback converter is verified by the OrCAD simulator. The main advantages of this converter ...
The output current, down to which the flyback converter should operate in CCM, is determined by selection of β in Equation 27. For example, β should be selected as 0.15 so that the converter operates in CCM down to 15% of the maxim output load current. The ripple in the prim...
In this paper, the boost-flyback power converter is controlled by peak-current mode with compensation ramp. The closed-loop analysis is performed to guarantee operation conditions such that a period-1 orbit is attained. The converter is considered as a piecewise linear system, and the closed-...
