CCFL applications consist of either a Royer-type DC-AC inverter or a full-bridge converter topology. Typically, CCFLs are powered from a 12 Vdc voltage and the Royer topology is the best choice when the output power is less than 12 W or when the number of lamps per modules is one or two. When the number of lamps per module is one or two, a low-cost circuit implementation is the best choice due to its functionality. In other cases, the full-bridge topology is more desirable.

Abstract
CCFL applications consist of either a Royer-type DC-AC inverter or a full-bridge converter topology. Typically, CCFLs are powered from a 12 Vdc voltage and the Royer topology is the best choice when the output power is less than 12 W or when the number of lamps per modules is one or two. When the number of lamps per module is one or two, a low-cost circuit implementation is the best choice due to its functionality. In other cases, the full-bridge topology is more desirable.File in questo prodotto:
