Design and construction of a low cost power inverter with an output voltage range from 220v – 240v.

Abstract

Power inverter is an electrical appliance that can be used with DC battery as an alternative source of energy supply in the event of power failures and energy crisis. It is cheap, clean, very conducive and silent when in operation and a very reliable source of power supply as to generator. Modern research and technologies have shown that inverter is one of the cheapest forms of energy generation. Throughout the world, it is readily available and can be partner to solar energy particularly using photo-voltaic cells (PVC) or solar panel arrays, with a battery bank as a reservoir to collect and store solar energy in large scale power generation/production for rural and very remote areas’ electrification project in the Nation. Sine wave, modified sine wave, square wave, cotek and power master from http://www.inverter.html. Most domestic appliances such as personal computers, television sets and lighting systems among others, operation has largely been controlled by hydro-electric power supply [National Grid]. This is not much a reliable source of energy due to the persistent power failure from our only reliable Nation Grid in the country, which has been the result of low water level in the dam(s) during dry seasons, faulty underground cables and transformer failures. the current energy crisis that is happening in Uganda and such experiences are seriously estimated worldwide in the near forthcoming as a result of unfavourable climatic change. This development therefore seeks to use inverter with the help of 12V DC battery as an alternative source of energy in the wake up of these challenges to power household appliances.
