DIY Uninterruptible Power Supply to the Rescue!

Much of the country’s power source rely on hydro power plants, and does rely on water. These last two months, we’ve experience rotating brownout and it’s kinda messing up everything. Long hours of not having electricity are torture to everyone. It also messes with my work, and gets lots of backlogs. What I really don’t like about brownouts is that it comes like thief, which ruins everything when you’re doing something on your computer (reports, excel files, powerpoint presentations, etc.) and forgot to save it.

I don’t want to experience those nightmares anymore so I searched for an affordable UPS in the market. But buying the device is too mainstream, so why not create my own? I searched the big G for tutorials on how to make your own UPS and found this one.

As you can see on the circuit drawn on this project, the diagram shows how the batteries take control during a outage in electrical power supply.  The input to the primary to the primary winding of the transformer is 240V as stated. If the value is at least 12 Volts running, the secondary winding can be raised for up to 12 Volts.

The circuit in this project was designed to offer more flexible pattern where we can use different regulators and batteries to produce regulated and unregulated voltage if we want it to be customized.

So now I will have no worries if an outage will come. Now that is awesome!
