Forced frequency resonant flyback

WebAug 16, 2008 · If the quasi-resonant flyback converter has a turns ratio of 20, and an output voltage of 5 volts, VRO will be 100 volts. So for a bus voltage of 375 volts, the switch will turn on at 275 volts. If the effective output capacitance, COSSeff , is 73 pF, and the switching frequency, fSW , is 66 kHz, the power loss will be 0.18 watt, i.e., (Eq. 2). 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).
