Forced frequency resonant flyback

WebFeb 8, 2024 · That being said, the power delivered by a discontinuous conduction mode (DCM) flyback depends on the frequency and peak current. Therefore, staying above 30 kHz is one thing but you may want to operate closer to 50-60 kHz to reduce the peak current and limit the transformer size. WebFeb 3, 2024 · The patented forced-frequency-resonant (FFR) switching scheme is implemented by means of a digital algorithm, which is configurable via parameter settings (UART port is included) to meet application requirements and the conversion efficiency of international regulatory standards (i.e., EU CoC version 5 Tier 2 and DoE Level VI).
