The purpose of this project is to design and construct 12V DC to 230V AC inverter with a frequency of 50Hz. The components that were used to construct the inverter consist of SG3524, MOSFET IRF3205, and a center tap transformer. Few capacitors, resistors, and variable resistor port were also used. The design and construction was done using locally sourced components. The basic principle of operation is based on an oscillator designed to produce an alternating e.m.f. of known frequency and wave form using SG3524 whose frequency is set to 50Hz and 12V DC from a regulated DC power supply to produce a 230V AC at the output of a transformer. A 4W bulb was connected as load to the inverter. A digital multi-meter was also connected at the output of the transformer and the digital multi-meter reads 230V AC. Overall, the circuit performed satisfactorily.
