But sometimes loses power, it runs out of energy for working as a power outage. We need to use a UPS circuit UPS (Uninterruptible Power Supply) circuit Diagram diagram. Some call the emergency backup battery systems. It can be applied to many applications. When the power goes, the battery can provide backup power automatically.
The power supply can be single or dual. A single supply creates only one voltage, but a dual supply produces two voltages, one positive and one negative. This article focuses on the dual power supply in particular. So we have decided that in this tutorial, we are going to make a “Dual Power supply from a single battery”.
This build is made up of four subsystems. The first is the DC power supply from the battery pack, with the first filtering capacitor (leftmost C1 in the basic circuit) and a power switch (power subsystem diagram). The filtering capacitor does the job for all the regulator subsystems, so we only need it once.
This article discusses a simple uninterruptible power supply that can come in handy in various situations. The design contains a rechargeable Li-Ion battery, battery protection and charging circuitry, and a 12V step-up module. It features two 12V outputs and a standard full-size USB port for charging all sorts of mobile devices.
A basic power supply circuit will fundamentally require three main components for providing the intended results. A transformer, a diode and a capacitor.The transformer is the device which has two sets of windings, one primary and the other one is the secondary.
These simple and cheap 6-volt power supply circuits with a 6V backup battery system or 6V UPS circuit diagram. First, the AC power 220V is entered to through input of transformer-T1 to reduce voltage as 9VAC. Then, the wire connected to four diode D1-D4 as bridge rectifier became to 11VDC.
See simple UPS circuit diagram as small emergency backup battery systems can apply applications, when goes out. It will keep power on.
