CIM(Current Injection Method)을 이용한 Charge-Pump 방식의 Plasma Backlight용 고압 Inverter

Charge-Pump High Voltage Inverter for Plasma Backlight with Current Injection Method

Charge-pump high voltage inverter for Plasma backlight with CIM(Current Injection Method) is proposed in this paper. Adoption of ERC is a new attempt in high voltage inverter so that it is not only energy recovery but also improvement of discharge stability and system unstability which is interrupted by noise. Using a charge-pump technique enables low voltage switches to be usable, the cost can be reduce. CIM is adopted to achieve high speed energy recovery in proposed circuit. Operations of the proposed circuit are analyzed for each mode. The proposed circuit is verified to be applicable on a 32 inch plasma backlight panel by experimental results.
