Abstract:
A multiple output synchronous rectification circuit comprising:a single transformer coupled to a single input voltage; andat least two synchronous rectifiers, each of the at least two synchronous rectifiers being coupled to the transformer via a winding, each of the at least two synchronous rectifiers including a first controlled switching device coupled to the winding, wherein at least one of the at least two synchronous rectifiers includes a magnetic amplifier core coupled to a magnetic amplifier, wherein the first controlled switching device of the at least one of the at least two synchronous rectifiers is coupled to the winding via the magnetic amplifier core, wherein the magnetic amplifier resets the magnetic amplifier core to delay the input voltage across the at least one of the at least two synchronous rectifiers for a predetermined amount of time and each controlled switching device operates in a zero voltage switching mode.
