This power supply is designed for Hi fi Audio applications.
C1 & C2 capacitors to filter higher frequency noise from the transformer
secondary AC lines at the diode bridge.
AC input received from transformer is converted in to DC by Bridge rectifier D1.
Always use heatsink with bridge rectifier because without heatsink the bridge rectifier will gets hot.
So use suitable heatsink to get full output current from the bridge rectifier.
C3, C4, C5 & C6 are in parallel with the bridge diodes to reduce high frequency noise and ringing of the diode.
C7 & C8 capacitors to filter higher frequency noise right at the DC output of
the diode bridge.
C9, C10, C11 & C12 are the large reservoir capacitors to supply large current demands and stabilize the supply rails to minimize low frequency fluctuations.
C13 with R1 & C14 with R2 are to decouple the large electrolytic capacitors and reduce
C15 & C16 are Film capacitors to filter high frequency Noise.
LED D2 with R3 & LED D3 with R4 are to indicate supply status.
JP1 & JP2 are Wire Jumpers of Copper wire of Suitable Gauge.
As we can see in the circuit diagram, C9 and C11 is separated by jumper JP1, C10 and C12 is separated by JP2. in normal case a simple wire connector is sufficient.
Advanced Features -
PCB designed with thick copper tracks & large solder pads to facilitate straightforward placement and soldering of components.
