Among them, the first pin of the rectifier bridge BD1 is connected to the neutral line of the 220V mains, the third pin of the rectifier bridge BD1 is connected to the live wire of the 220V mains through the fuse FR1, and the fourth pin of the rectifier bridge BD1 is grounded, rectifying The second pin of the bridge BD1 is respectively connected to the VCC end of the power control chip U2 and one end of the transformer T1 in the main circuit 11 of the flyback switching power supply, and the other end of the transformer T1 in the main circuit 11 of the flyback switching power supply is connected to the power control Pin 6 of chip U2. The rectifier bridge BD1 is used to convert 220V AC power into DC power, and the flyback switching power supply main circuit 11 is used to step down the DC power rectified by the rectifier bridge BD1. The connection method between the power control chip U2 and other components is a mature solution, which will not be repeated here.

In this specific implementation manner, the specific model of the rectifier bridge BD1 is MB6S, and the specific model of the power control chip U2 is BP3122B.

Normally, pressing the on/off key on the remote control of the household appliance will make the TV enter the standby state. The socket enters the infrared signal matching stage, and the infrared receiving head IR can receive the infrared signal emitted by the remote control of the household appliance and cooperate with the single-chip microcomputer U1 for matching.

Among them, the standby power consumption of the set-top box is the largest, usually around 14W-15W, while the standby power of other devices is also around 1W, and most families usually have multiple set-top boxes and TVs. As a result, the standby power in the entire home environment can reach tens of watts.
