Design and realization of a single-phase inverter with numerical control based on an Atmega32

This article aims to develop the control circuit of a single-phase inverter following our previous studies on the MPPT control and photovoltaic systems, this inverter produces a pure sine wave with an output voltage that has the same amplitude and frequency as Network voltage. A microcontroller, based on advanced technology to generate a sinusoid with fewer harmonics, less cost and a simpler design. The technique used is the sinusoidal pulse width modulation generated by the ATmega32 microcontroller. The designed inverter is tested on various AC loads and is primarily focused on applications such as an AC lamp. Proposed model of the inverter can improve the waveform of the inverter and control the dead time. The finished design is simulated in Proteus to ensure output results that is virtually verified.
