چکیده
Fluorescen t power SUPPlY Dimmer I Electronic bal last I Lamp IAn electronic ballast for fluorescent lamp lighting using a new resonant inverter is proposed. The electronic ballast has high efficiency, light wcight and small sizc bccause the resonant inverter operates at high frequencies with low switching losses. The inverter output power can be continuously controlled by regulating the L-C resonant tank encrgy of the resonant inverter with ease. The lighting system using this resonant inverter has the prominent features of high efficacy [ImnV], low flicker, low noise, wide dimming rangc, and soft starting. The basic operation principle of the proposed inverter and the dimming control scheme are dcscribcd and the experimental results are prcscnted.

A Class E Resonant Inverter for Use as Electronic Fluorescent Lamp Ballast
Class E Resonant Inverters are theoretically capable of delivering any power to a load and achieve 100% efficiency at any frequency of operation. In practice efficiency in the “high 90's” can be achieved into megahertz frequencies regardless of inverter output powers. The topology also allows the manipulation of output power through sub-optimal operation, with a negligible efficiency penalty. T...

متن کاملAnalog versus Digital
W hen considering alternative approaches to the design of dimmable electronic ballasts for fluorescent lamps, the lamp power regulation method employed is the critical factor. It determines the linearity (i.e., the linear response of the light output with the dimming control input), the smoothness of dimming and, most importantly, the stability of the light output. Both digital and analog appro...
