Title: Innovations of Vijay K. Maddali in Electrical Engineering
Introduction
Vijay K. Maddali is a prominent inventor located in Rockford, IL, with an impressive portfolio of 35 patents. His work primarily focuses on advanced methodologies and systems in the realm of electrical engineering, particularly in power generation and fault isolation.
Latest Patents
Among his latest innovations, the "Automatic Fault Isolation Methodology" stands out. This patent describes a method and system that aims to respond efficiently to a fast trip protective element trip in a generator system. The system re-excites the generator upon such a trip and assesses whether the fault originates from the generator or an attached load. If the load is identified as faulty, the system temporarily disables the fast trip protection element to allow the load to clear its fault, thereby ensuring the generator remains operational.
Another significant patent by Maddali is the "Overvoltage Limiter in an Aircraft Electrical Power Generation System." This invention details a generator setup that includes a permanent magnet generator, an exciter, and a main generator mounted for rotation on a shaft. The generator control unit includes a circuit that manages current flow from the permanent magnet generator to the exciter. The innovation incorporates an overvoltage limit controller that modulates a switch based on error measurements between actual output voltage and desired voltage thresholds, thereby protecting the system from overvoltage conditions.
