THE DESIGN OF A 500WATTS UNINTERRUPTIBLE POWER SUPPLY WITH VOLTAGE LEO INDICATOR [INVERTER]

ABSTRACT

As new ideas emerge and technology advances, and businesses become more reliant on technology for basic operations, system availability becomes increasingly important.

Uninterruptible power supplies [INVERTER] ensure a continuous supply of electricity to critical equipment that cannot be turned off unexpectedly. They are commonly associated with telecommunications equipment, computer systems, and other facilities such as airport traffic control systems, where even a brief commercial power outage can result in injuries or fatalities, severe business disruption, and data loss.

The 500watt UPs is intended for use in such circumstances. This UPs [Inverter] is ideal for small businesses and home PCs that require adequate power due to its conversion design, which provides clean square wave power to the critical load and with the battery protection against power failure.

CHAPTER ONE

INTRODUCTION

Because of the poor quality of power supply these days, standby power is an absolute necessity. Current AC power lines are characterized by spike surges, transients, sags, and noise. This causes electronic equipment to fail, and without adequate protection, all electronic equipment is at risk.

The primary function of a UPS is to provide an uninterruptible power supply to the equipment it protects. For example, because an electric device plugged into the wall has only one source of power, if there is a blackout, the electricity is cut and the device immediately turns off. A UPS changes the equation entirely by providing its equipment with two power sources. UPs are built with one source and another source in mind.

The battery contained within the UPs is one of the secondary power sources, which kicks in if the primary is disrupted.

While there are many less expensive methods for providing some degree of protection for one’s PC (for example) from power problems, none of them can protect your system as well as good UPs with a voltage analyzer.

The concept of a UPs is fairly obvious from the name. Special circuitry and batteries, in addition to filtering, enhancing, or modifying utility power, are used to prevent the PC (for example) from losing power during a disruption (black out) or voltage sap.

SCOPE AND SPECIFICATION

The scope of the project is limited to the creation of a standby UPs with a voltage LED indicator.
