Coreless PCB transformers with multiple secondary windings for complementary gate drive circuits

Abstract

This paper describes the modeling and implementation of coreless PCB-based transformer with `multiple' secondary outputs. This new PCB-transformer has been successfully applied in complementary gate drive circuits in a novel low-profile power converter with high power density and converter bridge. The PCB-based transformers do not require the manual winding procedure and thus simplifies the manufacturing process of transformer isolated gate drive circuits. The use of the multiple secondary outputs can in principle simplify the complementary gate drive circuits that are often required in many power electronics applications.
