CCFL inverter transformer

A CCFL inverter is an electrical inverter that supplies alternating current power to a cold cathode fluorescent lamp (CCFL). CCFLs are often used as inexpensive light units in electrical devices that are powered by direct current sources such as batteries Power-Transformers CCFL-Transformers CCFL Transformers.

TPS68000 CCFL Controller (FA2786-BL) Products Power Inductors RF Inductors Transformers EMI Chokes/Wirewound Ferrite Bead CCFL Inverters A CCFL inverter is a module or a device in a circuit that provides the power supply to a cold cathode fluorescent lamp (CCFL). It is called an inverter because it is supplied by a direct current (DC) source, and provides a different alternating current (AC) voltage output to drive the CCFL Cold Cathode Fluorescent Lamp (CCFL) Inverter Transformers are widely used to convert a low DC supply to a high voltage AC to drive, for example, LCD backlights. They employ a variant of SMPS technology to switch the DC using transistors (in a push-pull configuration) at high frequencies (40-80 kHz in our example) into the primary AN-13 LX1686 Direct Drive CCFL Inverter Design Reference 1.0 INTRODUCTION Two equally imp ortant but technically di verse components dete rmine overall per formanc e, reliability and cost of CCFL i nverter s.

Follow Us A cold cathode fluorescent lamp (CCFL) inverter is an electronic circuit that drives a CCFL, a gas-filled tube designed to produce light when the gas filling is ionized by electrical currents through the main terminals and through the gas inside the tube

The transformer in these supplies is called a photoflash transformer. There are several companies that make standard off the shelf transformers PCA, and TDK being two. These transformers are small, and have a 1:12 turns ratio typically. Now back to my experiment with the CCFL transformer. It essentially failed input capacitance, as opposed to a magnetic transformer's input inductance.3 Figures 1 and 2 show PZTs; the surprisingly small size is readily apparent. The form factor is ideal for constructing space efficient CCFL backlight inverters. A complete, prac-tical inverter appears in Figure 3 XFMRS would like to highlight our line of transformers for use in cold-cathode fluorescent lamp (CCFL) power supplies. Similar transformer series by other magnetics vendors have reached end-of-life status, but XFMRS still offers drop-in replacement components Not sure how the transformers are used to power each lamp - it's possible two or three such small transformers are used to power 2 or more ccfl tubes and they resorted to 2 or 3 transformers to reduce the height of the inverter and make the tv more appealing
