Title: The Innovations of Kozin Abe
Introduction
Kozin Abe is a notable inventor based in Hitachi, Japan, recognized for his contributions to electrical engineering. He holds two patents that showcase his innovative approach to power supply and electrical apparatus design. His work has significantly impacted the field, particularly in enhancing the efficiency and reliability of electrical systems.
Latest Patents
One of Kozin Abe's latest patents is a "Switch mode power supply having magnetically controlled output." This invention features a magnetically controlled switching regulator that manages output voltage using a saturable reactor. The saturable reactor consists of a first winding for output current and a second winding for reset current. The energy for resetting the reactor is sourced from a capacitor in the smoothing circuit for the output voltage. The design ensures that the reset current does not flow through a transformer, preventing saturation and excessive temperature increases, which allows for a miniaturized transformer core and improved output voltage control.
Another significant patent is related to a "Gas-insulated electric apparatus and method of detecting partial discharges." This invention involves a gas-insulated switchgear and bus, where an insulating-gas-filled metallic container supports a high-voltage electric conductor. The apparatus employs a differential amplifier to detect potential differences, enabling high-sensitivity detection of partial discharges along the insulating supporter.
