Abstract

A gate driver with Boot-strap chain is proposed to drive Multi-level PDP sustain switches. The proposed gate driver uses only one boot-strap capacitor and one diode per each MOSFETs switch without floating power supply. By adoption of this gate driver circuits, the size, weight and the cost of the driver board can be reduced.

본 논문에서는 Multi-level PDP 구동회로의 Sustain 스위치를 구동하기 위해 Boot-strap chain 방식의 Gate driver를 제안한다. 제안된 Gate driver는 한 개의 High-side N-MOSFETS를 구동하기 위해 별도의 Floating power supply 가 필요치 않고 한 쌍의 다이오드와 캐패시터만을 사용한다. 제안 Gate driver 회로를 적용함으로서, Multi-level PDP driver의 가격과 무게 및 부피를 줄일 수 있다.
