The printed circuit boards are used extensively in the electronic industry with applications ranging all over the consumer electronics spectrum. The single sided PCBs dominate the market in terms of sheer volume as they are least expensive and provide a quick and cost effective solution to most problems in electronic circuits.

Printed Circuit Boards in Uninterrupted Power Supplies

Single sided PCBs have low probability of manufacturing issues. They are popular, common and are most familiar with most PCB manufacturers. Though theses PCBs are usually simple but still they are also reemployed in highly significant and complex electronic devices i.e. Power supplies, Relays, Radio, surveillance etc. Double sided PCBs are mostly used in industrial controls, control relays, HVAC systems, hard drives, printers, amplifiers, test equipments etc. The Multi layer PCBs are mainly used in computers, file servers, data storages, GPS technology, X rays equipment, cell phone transmission and internal circuitry and enumerate number of other such complex integrated circuits.

We will look in greater detail the function of printed circuit boards in uninterrupted power supplies (UPS) devices. The need of uninterrupted power is now more evident than it ever was and with continuous increasing demand of power, some countries are facing power outages. In order to deal with the power outages problems, the uninterrupted power supplies i.e. UPS were invented.

What is an Uninterruptable Power Supply?

An uninterruptible power supply, also uninterruptible power source, UPS or battery/flywheel backup is an electrical apparatus that provides power to the system which it is connected to i.e household assembly of electricity run devices, offices, computer run etc when the power from the main grid gets disrupted or cut off and it can also provide emergency power to a load when the input power source, typically mains power, fails.

UPS is a device that provides battery backup when the electrical power fails or drops to an unacceptable voltage level. Small UPS systems provide power for a few minutes; enough to power down the computer in an orderly manner, while larger systems have enough battery for several hours. In mission critical datacenters, UPS systems are used for just a few minutes until electrical generators take over.

UPS systems can be set up to alert file servers to shut down in an orderly manner when an outage has occurred, and the batteries are running out.

What is the working Principle of Uninterrupted Power Supply?

From basic principles in terms of application, UPS is a device that contains stored energy in order to inverter as the main component, regulated stable frequency and output power protection equipment mainly by the rectifier, batteries, power inverters and static switch of several components.

1) Rectifier:

Rectifier is a rectifier device, simply means that the exchange of (AC) into direct current (DC) devices. It has two main functions: First, the alternating current (AC) into direct current (DC), through the supply of filtered load, or the supply inverter; second, to provide battery charging voltage. Therefore, it is also play a role in charger.

2) Battery:

UPS battery is used as a storage energy device, which consists of several cells in series, with a capacity to maintain its size determines the

discharge (supply) time. Its main function is: When the electricity is normal, the energy converted into chemical energy stored in the battery internal; when the electricity fails, the chemical energy into electrical energy provided to the inverter or the load.

3) Inverter:

The inverter is a DC (DC) into alternating current (AC) device. It consists of inverter bridge control logic and filter circuit.

The most effective designs of the uninterrupted power supplies UPS are done on the printed circuit boards which has led to the evolution of highly reliable household printed circuit boards.
