UPS is an abbreviation of Uninterpretable Power Supply. It is an electronic product used to provide backup power for sensitive devices in case their normal power failure or blackout. Given UPS Schematic Circuit Diagram with its component list is a complete guide to build standard power backup. Its power is measured in Watts or in Kilo Watts. UPS are widely used in 3rd world countries like in India, Philipines, Bangladesh, Pakistan because of regular load shedding due to lack of power resources. Given UPS Schematic Circuit Diagram will convert 12volts DC to 230 Volta AC . 12 Volts Battery needs to be attached as a source or input.

Inverter Features & Functionality Description
The project presented is really a 2KW or 2KVA power inverter created for backup throughout utility and appliance failures. The inverter is passionately known as the ‘I2K’ for 2 reasons: It features a 2kVA output power capacity
UPS Schematic with code is based on microchip pic microntroller PIC16C84 running at 3.6864MHz crystal,This inverter is of the traditional ferroresonant design using large step-up transformers nevertheless the pulse-width modulated signals which feed the transformers are produced in tangible-time with a PIC RISC microcontroller. The microcontroller senses AC output current with an 8-bit ADC then changes the heart beat width accordingly utilizing a closed control loop formula. The functions of waveform timing, pulse width adjustment, and error control (shutdown when overload happens) are completed in software making upgrades simple to accomplish.
Many commercial inverters examined, including individuals employed for PC UPS usages, won’t supply the enormous start-up power needed by many people motors — especially single phase motors under load for example individuals based in the average gas furnace. This design provides individuals needed power and, throughout one test, was observed to transform over 2kVA of energy (The input current exceeded 200A at 12VDC for many seconds before the motor began). Software charge of the inverter enables the inverter to become overloaded for time before shutdown happens giving the motor time for you to start.
The inverter continues to be examined on 1/3hp single phase motor loads in addition to with large resistive lots of over 1500W and it has carried out well. Energy factor correction was discovered to be needed with large motor loads and it has been incorporated within the design.
Efficiency from the inverter (Energy Output / Energy Input) driving a number of both resistive and inductive loads ranges between 71% and 82%. By having an enhanced sine-wave formula it’s felt the inverter can approach the theoretical efficiency limit of 92%.
