This research work explores the possibility of designing and constructing a microcontroller-based circuit that functions as an inverter and automatic voltage regulator. The circuit was developed with proteus® software and its firmware was developed using Mikrobasic® software. The circuit, which has two modes, namely the inverter mode and the automatic voltage regulator mode, was built around a PIC16F877 microcontroller. In the automatic voltage regulator mode, the constructed circuit maintained the output voltage between 215V and 235 volts for input mains voltage variation between 160 and 265 volts. In the inverter mode, the circuit produced a modified sine wave whose ischolar_main mean square value varies between 210 and 225 volts when it was loaded up to 1kW maximum output power.
