Design and Implementation of a 500 Watts, 12d.C Volt/230a.C Volt Inverter with Overload Protection CapabilityINTRODUCTIONBackground to the projectAn inverter is an electronic device that has the ability to convert the direct current (dc) from the battery or solar cells (panels) to alternating current (ac) which is the convectional form that powers many electrical appliances. Most standard appliances are designed to accept only AC (alternating current) voltages because that's how electricity is supplied from the grid. To run an electronic device from a DC (direct current) source you obviously need to transform DC into AC. A device that converts electricity from DC form to AC form using electronic circuits is known in power industry as inverter. Sometimes, the same term is used in digital electronics for a circuit that switches the logic level of a signal. To avoid confusion, the device we are talking about is a power inverter. Its typical application is to convert a 12V battery voltage (direct current) into conventional residential voltage. Inverters are used in a wide variety of applications like small car adaptor to large grid-tie systems that can supply electricity to an office or even entire home.Reasons and Problem leading to formulation of the projectIn rural areas electric power is a problem, there is high degree of power cut-off or no electricity. This makes people in these areas face difficulties in using electronic equipment like mobile phones, radios etc.
