This paper discusses the design scheme of an inverter system which converts the DC voltage collected from a battery into AC voltage. The output is a sine wave, with the voltage at 220v and 50 Hz frequency output. The system consists of a bipolar transistor driver and push pull inverter with step-up transformer circuit and a passive filter. The power supply supplies the DC voltage needed to activate the opto couplers, which are connected to the bipolar transistor driver of the push pull inverter circuitry. The opto-couplers work as an isolation for the power inverter circuit. Pulse Width Modulated (PWM) pulses are generated by a microcontroller Arduino mega and provided to the trigger of driver circuitry. The inverter power outputs a PWM sine which is later conditioned to pure sine by step-up transformer. Finally, at the end of the inverter circuits is equipped with a low pass filter to suppress distortion, to produce a full-wave signal output which is closer to pure sine.
