一、彩电开关电源简介开关电源是彩色电视机中故障率最高的单元电路之一。其机芯类型繁杂,电路结构复杂。彩电开关电源的检修已成为家电检修技术中的难中之难。 1.彩电开关电源的分类说彩电开关电源机芯繁杂,电路复杂一点也不过分。在我国现有的彩色电视机中,开关电源有一百多种相互不完全相同的电路结构。仅开关电源中采用的厚膜电路就达80种以上。按照开关器件与负载的连接方
First, the color TV switching power supply Introduction Switching power supply is one of the highest failure rate of the color TV unit circuit. The type of complex movement, the circuit structure is complicated. Maintenance of color TV switching power supply has become a difficult home appliance repair technology difficult. 1. The classification of color TV switching power supply that color TV switch power supply movement complex, circuit complexity is not excessive. In China’s existing color TV sets, the switching power supply has more than 100 kinds of circuits that are not identical to each other. Only the switching power supply used in the thick-film circuit reached 80 or more. Follow the connection of the switching device to the load
