Energy-saving type direct current power supply line bar

Abstract

The invention discloses an energy-saving type direct current power supply line bar which comprises a shell, a direct current conversion circuit board and a plurality of direct current power supply ports, wherein the direct current conversion circuit board and the plurality of direct current power supply ports are arranged on the shell; the direct current conversion circuit board is connected witha mains supply socket by a wire; a plurality of direct current output end of the direct current conversion circuit board are respectively connected with the direct current power supply ports; the direct current conversion circuit board comprises an overcurrent protection device, an EMI filtering circuit, an input rectification filtering circuit, a main conversation circuit and a synchronous rectification module which are sequentially connected; an output end of the main conversation circuit is connected with a VCC voltage circuit; the VCC voltage circuit is connected with a PWM control circuitby a voltage feedback circuit; and an output end of the PWM control circuit is connected with the main conversation circuit. The energy-saving type direct current power supply line bar can only generate standby power consumption of one power supply in a standby state, so that energy consumption is saved. Meanwhile, a material for producing the line bar is saved, a complex power supply line wiringoperation is also avoided, and the problems of large wiring occupied space, no attraction and the like are solved.

Description

technical field [0001] The invention relates to the technical field of power supply, in particular to an energy-saving DC power supply line bank. Background technique [0002] Now there are basically electronic devices such as set-top boxes, routers (WIFI transmitters), Internet modems, network boxes, audio and video boxes, etc. at home, and each device basically needs to be powered by a 12V power supply. First, in the standby state, every The power supply of each device is in the standby state, and according to the current global six-level standard, the standby power of each power supply must be less than 0.075W, or 0.15W, so the more boxes used in the family, the more power supplies. In standby mode, more grid power is consumed. [0003] At the same time, there are 3-5 power supplies and 3-5 power output cables, audio and video cables, high-definition cables, network cables, etc. behind each TV set in every family, which are like spider webs, which are very unsightly and ...
