HEAT RADIATION SUBSTRATE, MANUFACTURING METHOD THEREOF, POWER SUPPLY UNIT, AND PLASMA DISPLAY DEVICE

摘要

PROBLEM TO BE SOLVED: To solve the problem of the influence on minimization of power loss of a plasma television because a conventional coil used for a power supply unit of PDP (plasma display panel) varies in inductance value (L component) by upto ±20%, with capacitance load (C component) of the plasma panel varying as well.;SOLUTION: A sheet-like heat conductive resin part 10 embedded with a lead frame 12 whose one part is a coil 15 is fixed on a metal plate 11 comprising at least one hole 16, and a ferrite core 17 is inserted in the hole 16 formed around the center of the coil 15, to adjust an inductance value (L component), resulting in suppressed power loss of the plasma television.;COPYRIGHT: (C)2008,JPO&INPIT
