WebbThe circuit diagram shows a complete power supply in which the mains is isolated by the double-pole single-throw (DPST) on/off switch, S1. T1 then acts as a step-down transformer (turns ratio 18.3:1) whilst D1-D4 form a full-wave bridge rectifier. C1 is the reservoir capacitor whilst R1 and C2 act jointly as a low-pass smoothing filter. Webb31 okt. 2016 · The Power Supply Circuit Diagram So, the final circuit looks like this: Parts List The total cost of the components is about $12-15. The most expensive component is the transformer (about $10). Finding …
