Power Tips #76: Flyback converter design considerations - EDN

WebThe flyback’s output filtering also differs from the forward supply. For a flyback, the output L-C comprises the primary inductance of the power transformer and the output capaci - tor, C OUT1. The resulting filtered DC output voltage at V OUT1, like the forward, is proportional to D and the power trans-former’s turns ratio, N. Continuous mode has the following disadvantages, which complicate the control of the converter: • The voltage feedback loop requires a lower bandwidth due to a right half plane zero in the response of the converter. • The current feedback loop used in current mode control needs slope compensation in cases where the duty cycle is above 50%.
