Title: Innovations of James M Gregorich
Introduction
James M Gregorich is an accomplished inventor based in Merrimack, NH (US). He holds a total of 3 patents that showcase his expertise in electrical engineering and power supply technologies. His innovative contributions have significantly impacted the fields of plasma technology and power supply systems.
Latest Patents
One of his notable inventions is the Plasma Torch Pilot Arc Circuit. This invention establishes a pilot arc current in the channel between the torch electrode and torch tip at a first target level, which is greater than a predetermined minimum current sufficient to maintain a stable pilot arc. After a period of time following pilot arc initiation, the pilot arc current is reduced to a second target level, minimizing wear on the torch parts. The pilot arc current is established and maintained as a function of a pilot arc reference signal, and pulsing the pilot arc current assists in main arc transfer and enhances pilot arc stability.
Another significant patent is the High Power Factor Switched DC Power Supply. This invention features a full-wave rectifier for rectifying an AC line voltage and a power regulator that includes switch means responsive to a control signal for controlling the application of the rectifier output to a load. The control circuit produces a switching control signal that is directly related to the difference between the power supply DC output voltage and a self-generated constant reference. This invention avoids the square law dependency of prior art high-power-factor power supplies and can operate over a broad input dynamic range.
