Title: Wolfgang Peprny: Innovator in Power Supply Technology
Introduction
Wolfgang Peprny is a notable inventor based in Vienna, Austria. He has made significant contributions to the field of power supply technology, holding a total of four patents. His work focuses on innovative methods for operating switched mode power supplies, which are crucial in various electronic applications.
Latest Patents
One of Peprny's latest patents is a method for operating a switched mode power supply with the return of primary-side stray energy. This invention relates to a method for operating a switched mode power supply as an isolating transformer. In this method, magnetic energy is stored in the core of a transformer during a storage stage via a primary coil connected to an intermediate circuit current. The stored magnetic energy is then delivered to a load in a subsequent discharge phase, primarily through a secondary coil, with a small portion discharged on the primary side. The energy discharged on the primary side charges a capacitor, ensuring that the capacitor current remains above the secondary current multiplied by the transmittance ratio of the transformer.
Another significant patent is for an asymmetric half-bridge with reduced switch load. This circuit arrangement features two serially connected semiconductor switches linked to a voltage supply. A primary winding of a transformer is connected between the semiconductor switches, with diodes strategically placed to manage the flow of current. This innovative design enhances the efficiency and reliability of power supply systems.
