AUTOMATIC POWER INVERTER

INTRODUCTION

A power inverter is an electronic device or circuit that change DC voltage to AC voltage.

Inverter can be connected to a battery and produce AC power to run various electrical items such as lights television computers and other power tools.

PROBLEM STATEMENT

In our country the problem of electricity is common which lead to power off without any notification, causing to stop all activities depending on electricity or distraction at home, shops, offices, etc.

There for this Automatic power inverter will hold the load immediately when the power is off and prevent all disturbance and distraction which may occurs.
