    Abstract

    This paper presents harmonics improvement in a DC-DC converter based line frequency inverter for domestic lighting loads. Harmonics problem in power electronics converters is not a new phenomenon as over the decade succeeded in effecting our power output. It is also recognized to be a problem that would destabilize the reliability of power system, to overcome this problem, the design of a suitable filter must be implemented. For this project, a LC Low Pass filter has been chosen to reduce the harmonics in the system to get a 5W power output. The input voltage is a DC battery having power capacity of 24W, 6V DC has been chosen as the input DC voltage and it will be stepped up to 12V DC using the push-pull converter. A voltage regulator circuit is installed to regulate the voltage to the microcontroller chip PIC16F877A that has been used as the main control unit for this project having the capability to generate Pulse Width Modulation (PMW) signals to drive the MOSFET turn ON and OFF. The 12V DC will be inverted to 220V AC using the line frequency inverter. The bulb having the power capacity of 6W is used as the output lighting loads.
