Coreless PCB transformer in HB ZVS DC/DC converter for vehicle FPL lamp power circuit

Coreless PCB 변압기를 이용한 자동차 전원 구동 FPL 램프 전원 회로

This paper proposes the application of coreless PCB transformer to Half-Bridge (HB), Zero-voltage-Switched (ZVS) DC/DC converter for FPL lamp with electronic ballast in vehicle. The designed 5 coreless PCB transformers for ballast driving voltage are parallel-connected in primary windings and series-connected in secondary windings. Coreless PCB transformer is designed to have spiral winding in order to transfer higher energy. The computer simulations of the proposed power circuit show coreless PCB transformer to have good performance.
