Variable power supply circuit from fixed voltage regulator the fixed voltage regulator is used to offer fixed voltage at the output terminal and does not depend upon the input voltage supplied here is the circuit producing variable voltage power supply designed using fixed voltage regulators circuit diagram working. Diagram of a power supply circuit. 1 development history of switching power supply the switching power supply has replaced the transistor linear power supply for more than 30 years the first to appear is the series switching power supply the main circuit topology is similar to that of the linear power supply.

This chapter provides a fresh start regarding another section of diode circuits this gives an introduction to the power supply circuits that we come across in our daily life any electronic device consists of a power supply unit which provides the required amount of ac or dc power supply to various. In this project we construct a dual power supply circuit to convert 220v ac supply in to +12v and -12v dc supply, that is why it is named dual power supply as we get positive and negative 12v power supply at the same time.. Some single supply op-amp circuit might be used in some application, but it rarely has perfect linearity near the zero level since it has very low drive in the feedback path, so negative supply could be the only solution sometimes..
