Circuit Diagram Variable Power Supply
View Circuit Diagram Variable Power Supply Gif. Variable power supply circuit diagram. The above universal power supply circuit provides a variable voltage between 3 to 30v, the maximum current of 1.5a and addition of modules can provide a higher current.
The main circuit of the switching power supply is composed of an input electromagnetic interference filter (emi), a rectification and filtering circuit, a power conversion circuit, a pwm controller circuit, and an output rectification and filtering figure 1.
I have also added practical circuit for ups in this article. The following diagram is the schematic diagram of variable power supply which will deliver 0 to 28v output voltage at 6a or 8a electric current. This circuit diagram shows you how to make a 5v to 12v variable dc power supply from a fixed 5v regulator ic 7805. A variable bench power supply is the most important tool for any diy maker cause while testing circuit it needs different values of.
