ABSTRACT
As the name of the project implies “Power Inverter”, is an electronics system that converts DC Energy (voltage) to an AC energy.  The major aim of this project is to design and construct a 1000VA Power inverter that is capable of powering loads of equivalent ratings, in the absence of power supply from NEPA or Generator.
The system (power inverter) consists of the AC mains sensor section, Relay/change over section, Battery charger section, oscillator section, Driver section, output amplifier section, inverter output transformer section and the power supply unit.  The power supply unit supplies the voltage that powers the circuit.  The AC sensor senses the presence of AC when there is NEPA and the relay connects it to the loads.  The battery charger charges the 12V battery when the NEPA as ON.
When NEPA fails, the relay switches the inverter to battery operating mode.  In this case, the oscillator is switched on the oscillator is the heart of the inverter system.  It generates oscillating pulses which result, to the conversion of the DC voltage from battery to AC voltage.  In this project, we used an IC SG3524N in the oscillator circuit.  The SG3524N is a 16 pins IC and its output is taken from pin 11 and pin 14.  It happens that when pin 11 is ON, pin 14 is off and vice-versa.  The output of the oscillator is connected to the output amplifier, which amplifies it to an appreciable level and this is connected to the two Driver channels.
The Driver section consists of MOSFET Transistors of ratings APT8030L.  The driver is of two channels A and B and each channel contains three MOSFETS.  The Driver section determines the power rating of the inverter.  Due to the nature of oscillator output, it happens that when driver channel A is switched ON, channel B will be off and vice-versa.  This result to an AC output of frequency 50HZ.  The output Transformer steps it up to 240V.  This is the principle of power inverter.
Inverter system is very essential.  It does not need fuel or manual operation, since it is automatic.  Hence it saves both time and energy and improves economy.  The inverter finds applications both in the industry and at home for powering sensitive loads or system like computer resource centres which need no power interruption.
