Microcontroller Controlled Inverter Application

Abstract

The limited use of fossil fuels has increased the interest in renewable energy sources. Renewable energy sources are generally direct current (DC) production. The popularity of inverters converting from DC to AC is increasing due to the generation of the generated DC signal and the current grid being alternating current (AC). In this study, a computer-controlled inverter was designed with the 16F877 microcontroller chosen as the model, and frequency and amplitude controls were realized with the serial communication system of this structure. A digital-analog converter (DAC) circuit is formed by connecting the R-2R ladder type resistor to the relevant ports of the microprocessor. With the codes written to the microprocessor, the signal response was taken from the DAC circuit, and the signal response at the ports was combined with the inverter and collector operational amplifier (op-amp) circuits, and the inverter design was completed.
