Power Supply Circuit

A power supply circuit is the way in which the components used in a power supply are connected and function together. The power supply circuit typically includes one or more transformers, rectifier diodes, capacitors, resistors, transistors and integrated circuits, together with a fuse or circuit breaker and possibly a switch and/or indicators. The power supply circuit is represented with a drawing (see power supply schematic) that symbolically illustrates the wiring of the circuit and the functional values of the components that it includes.
