Title: **Innovations and Contributions of Donald E. Alfano**
Introduction
Donald E. Alfano is an esteemed inventor based in Round Rock, TX, known for his remarkable contributions to the field of electrical engineering. With a total of 40 patents to his name, Alfano has pioneered innovative solutions that enhance the efficiency and performance of voltage converters and power systems.
Latest Patents
One of Alfano's notable recent inventions is the "Soft-start for isolated power converter." This invention employs a sophisticated method where the current flowing through an inductor on a primary side of a voltage converter is sensed and compared to a threshold peak current value. This comparison determines the appropriate time to end the ON portion of the voltage converter operation. Crucially, the secondary side of the voltage converter provides an indication of output voltage that is utilized in determining the threshold peak current value. During start-up, the primary side detects the output voltage indication supplied by the secondary side via an isolation channel. Initially, before detecting this indication, the primary side uses an increasing threshold peak current. Once it confirms the output voltage is being provided, the threshold peak current value is adjusted based on that output voltage indication, optimizing the soft-start process.
