ABSTRACT:
In a switching power supply including a step-up transformer having primary and secondary windings, wherein in each successive cycle of operation, during a first period of time a voltage pulse is applied across the primary winding for causing forward current in the secondary to flow through a shuttle capacitor and output capacitor connected in series with the secondary winding at this time, for charging the output capacitor to a voltage level approaching the voltage across the series circuit of the shuttle capacitor and secondary winding, and in an immediately following second period of time terminating the voltage pulse across the primary winding, and allowing flyback energy in the secondary winding to charge and be captured only by the shuttle capacitor for transfer to the output capacitor during the next cycle of operation.
