Abstract

The invention relates to the technical field of electronic engineering, in particular to a PDP power integration module and a method for manufacturing the same; the PDP power integration module is characterized in that a copper-clad layer of a ceramic substrate is provided with a signal lead pin, a power lead pin and a power control circuit, which are welded and fixed by soldering tin; the power control circuit consists of two IGBT power topological circuits; one of the power topological circuits consists of two IGBT semi-bridge circuits with unconnected C electrodes and E electrodes and is driven by a high-pressure drive IG; the E electrode of the upper arm IGBT and the C electrode of the lower arm IGBT are connected in series with an FRD respectively; the other power topological circuitconsists of two IGBT standard semi-bridge circuits with connected C electrodes and E electrodes and is driven by another high-pressure drive IC; the upper arm IGBT and the lower arm IGBT consist of two chips connected in parallel respectively; each IGBT is connected in parallel with a subsequent flow FRD; and the PDP power integration module has the advantages of simple operation, timely information feedback and the like.

Description

Technical field: [0001] The invention relates to the technical field of electronic engineering, in particular to a PDP power integration module and a manufacturing method thereof. Background technique: [0002] As we all know, plasma display panel (Plasma Display Panel) is referred to as PDP. It is a novel direct-view image display device following the cathode ray tube (CRT) and liquid crystal display (LCD). Plasma display has become an excellent video display device and high-definition computer display due to its outstanding image effect and unique digital signal direct drive method. It will be the best display screen for high-definition digital TV, and its growth rate is very fast in recent years . According to statistics, the PDP machine market occupied 1.7 million units in 2009, and grew at a rate of 20%, reaching 30 million units in 2015. [0003] The main domestic PDP manufacturers are Changhong, Hisense, Haier, Konka, Skyworth, TCL and so on. At present, its IGBT ...
