The power supply circuit is a high-power circuit,we should pay attention to the down-lead,or it will not gain low-noise supply.The picture is the positive supply circuit formed by full-wave rectification and three terminal regulator.In the circuit,the ground of smoothing capacity C1 and regulator is connected to point A. Point A is a reference potential.The landlines of regulator will effect a lot to the circuit performance.If there is noise or hun in the landlines,it will emerge on the output end.There is smoothing current Ic charged and discharged by capacitor through The landlines of smoothing capacity C1.The capacity C2 is a vibration control capacity.
