ABSTRACT:
A transformer isolated switched power supply of the forward converter type which includes a clamping circuit for the switching unit of the power supply which recovers the energy stored in the transformer during each switching cycle without any need to dissipate the energy, and which also serves to reverse the flux in the power transformer during each switching cycle to restore the flux capacity of the power transformer to the same level as in other types of converter circuits.
