Title: Innovator Spotlight: Derek Albert Paice
Introduction
Derek Albert Paice, based in Palm Harbor, FL, is a distinguished inventor with an impressive portfolio of 28 patents. His innovations predominantly revolve around the development of advanced autotransformer technologies designed to enhance the efficiency of power conversion systems.
Latest Patents
Among his latest patents are two notable inventions: the Nine-phase Autotransformer and the Fifteen-phase Autotransformer. The Nine-phase Autotransformer is a polygon connected three-phase device featuring six windings per phase. It provides a reduced power rating nine-phase power source ideal for 18-pulse AC to DC power converters, controlling harmonic currents while minimizing the total kVA rating. Additionally, when used with a nine-phase AC to DC converter, its kVA rating is typically less than 48% of the DC load kW. This invention can also operate as an efficient double-wound transformer through additional isolated windings.
The Fifteen-phase Autotransformer, on the other hand, employs nine windings per phase. It serves as a fifteen-phase power source suitable for 30-pulse AC to DC power converters. The smart selection and connection of windings accommodate zero-sequence currents, including the third harmonic, and minimize the total kVA rating. For a 15-phase AC to DC converter, its kVA rating is generally less than 51% of the DC load kW, ensuring negligible AC line current distortion that meets rigorous harmonic specifications, with additional isolated windings for its double-wound transformer functionality.
