基于新型控制器FAN7710V的CFL镇流器

Ballast for Compact Fluorescent Lamp(CFL)Based on New Type Controller FAN7710V

FAN7710V是一种集成了CFL控制器和半桥MOSFET的组合IC。FAN7710V在310 V的DC电压上为CFL交付20 W的功率,并具有预热/触发功能。FAN7710V在点火后通过内部有源零电压开关(ZVS)电路检测开关操作,并能检测灯开路情况。该文介绍了基于FAN7710V的CFL镇流器原理与设计。

The FAN7710V is a combination IC integrated CFL ballast Controller and half-bridge MOSFET. The FAN7710V delivers 20 W to lamp at 310 V DC voltage and incorporates a preheating lignition function. The FAN7710V detects switch operation from after ignition mode through an internal active Zero-Voltage Switching（ZVS） control circuit and enables it to detect an open-lampcondition. This paper introduces the principal and design of CFL ballast based on FAN7710V.
