Abstract

ABSTRACT

The inconsistency of power supply in Nigeria has led to research in the quest of finding solutions in the power sector. The aim of this paper is to design and implement a pure sine wave inverter which can convert DC voltage to AC voltage at high efficiency and low cost. A dsPIC30F2010 microcontroller was used to generate the digital pulses needed to drive the H-bridge, which is made up of MOSFET drivers. By alternate switching the two arms of the H-bridge, the 48V DC voltage is converted to 34V AC voltage which is then boosted to 220V AC by the transformer. A low pass filter was used to filter out the high frequencies and thus isolate the harmonics so that a pure sine wave with 50Hz fundamental frequency was retained. Thus, the inverter produced a 220V, 50Hz AC output which can now be used to power any electrical/electronic equipment.
