DIY Raspberry Pi UPS HAT – An Uninterrupted Power Supply to Keep your Pi Safe during Power Failure

 

Raspberry Pi is a small or mini-computer that can be used in different types of small to large embedded, IoT, Industrial IoT applications. As this is a computer that could run different operating systems, a shutdown of this minicomputer is an important thing to ensure that everything is saved, the operating system properly ended all required tasks, and it is safe to turn the device off. Uncertain failure of power could damage the Pi as well as the operating system could also break down. Previously we have built many Raspberry Pi Projects and most of them needed to work 24x7 so, this project can act like a Raspberry pi UPS hat and can be used to keep our raspberry pi on during power failure.

DC to AC Inverter Circuit

Inverters are quite handy in time of power cuts. The most common type of inverter we see in everyday life is UPS (Uninterruptible Power Supply). We use UPS to keep PC (Personal Computer) running in the event of power cuts. UPS keeps up the power delivered until battery bank runs out.

UPS is a system which converts DC to AC. So, UPS takes DC power of battery as input and gives AC power as output. In this tutorial we are going to design a 100 watt 12v DC to 220v AC inverter. This Circuit is easy and you only need few capacitors, resistors, diodes and a transformer. So here the guide and schematics to build this inverter circuit.
