Fabrication of a Insulating Type Transmission-Line Transformer for High Frequency Inverter for Discharge Lamp

Abstract

In this study, a novel insulating type transmission-line transformer for electronic ballast has been fabricated and evaluated, which consists of a primary winding, a secondary quarter wavelength distributed constant circuit, an Mn-Zn ferrite core with a closed magnetic circuit, and a Ni-Zn ferrite plate for a bypass magnetic circuit.
