Title: Innovations from George Panagotacos: Pioneering Advances in Power Factor Correction and Light Sources

Introduction

George Panagotacos is a prolific inventor based in Corona, California, holding an impressive portfolio of 11 patents. His contributions in the fields of electrical engineering and lighting technology demonstrate a commitment to developing innovative solutions that address contemporary challenges.

Latest Patents

Among his latest inventions is a passive power factor correction incorporating AC/DC conversion. This innovative circuit is designed to convert an AC input voltage into at least one DC output voltage. It utilizes a diode bridge and a diode pair to rectify the AC input voltage, providing first and second rectified voltages. A resistor applies the second rectified voltage to a first capacitor that stores the first voltage, while a diode applies that voltage to an inductor. This inductor then applies the first rectified voltage to an output capacitor, effectively storing the DC output voltage. The passive power factor correction circuit aims to expand the commonly used full-wave bridge rectifier and subsequent storage capacitor, improving on design efficiency by targeting the size of the inductor while maintaining a power factor that rivals active PFC circuits. Early prototypes of this technology achieved an impressive power factor of 0.99 while driving a 100 W load.

Another significant invention by George is a light source that incorporates a secondary emitter conversion element. This light source features a primary excitation source capable of emitting electromagnetic radiation at a specific peak wavelength, with a secondary element designed to absorb a portion of that radiation and emit it at a longer second peak wavelength. The design is complemented by a non-imaging optical coupler, which optimally directs the emitted light and enhances its practical applicability in various optical systems.
