三星127 cm(50英寸)等离子V5屏模组的电源框图如图1所示。它同107 cm(42英寸)的三星等离子V5屏电源模组相比,除了VS驱动电路部分有较大更改以外,其他电路基本没有更改。从图1可以看出,107 cm(42英寸)等离子屏的电源和127 cm(50英寸)的电源很相似。除了VS电路驱动部分以外,只有个别元器件改变了编号,下面不再介绍整机原理,只介绍与107 cm(42英寸)电源不同的地方——VS驱动电路的工作原理。 Samsung 127 cm (50 inches) plasma V5 screen power module block diagram shown in Figure 1. Compared to the Samsung Plasma V5 with 107 cm (42 inches) power supply, the circuit has almost no changes except for the larger part of the VS driver circuit. As you can see in Figure 1, the 107 cm (42 inch) plasma screen has a similar power supply to the 127 cm (50 inch). With the exception of the VS circuit driver, only individual components have been changed. The whole principle will not be explained here. The only difference is the difference from the 107 cm (42 inch) power supply - how the VS driver circuit works.
