WebKeep in mind that the flyback circuit only generates an output pulse from the secondary winding when current is interrupted in the primary, in which case the primary voltage will exceed the input voltage by a large factor, and that voltage is further transformed by the Ns/Np ratio. ... The energy is stored in the magnetic-gap, which must be ... WebFlyback converters have relatively high peak and RMS currents, which may cause high conduction losses in the output diode rectifier. Synchronous Rectification can reduce these losses and improve the efficiency of the overall power supply. ... VDS_SENSE The pull-up resistor limits the current during the diode forward biasing: the pull-up and its ...
