<p><P>PROBLEM TO BE SOLVED: To take a current balance of a number of parallel crossroads of a circuit. <P>SOLUTION: Provided are a method and a device for balancing currents flowing in a number of parallel circuit crossroads, or, in some cases, in parallel fluorescent lamps. A single transformer with a multi-leg magnetic core is wound in a specific way for simply taking current balance. With the use of a conventional three-leg EE-type magnetic core accompanied by a coil winding introduced here, the currents are balanced in a circuit accompanied by three or more parallel crossroads such as cold-cathode fluorescent lamps (CCFL) of parallel connection. <P>COPYRIGHT: (C)2007,JPO&INPIT</p> |
