Design and Implementation of a Single-Phase Inverter for Low Power Requiring Systems

As semiconductor technology evolves, electronic systems that operate at low power are becoming more prevalent and attract the attention of researchers. In this study, a single-phase voltage controlled inverter was designed and implemented using the H-bridge topology and Pulse Width Modulation (PWM) technique for systems requiring low power. MOSFETs and ATMEGA328P-AU microcontroller were used as switching circuit elements in order to obtain high efficiency in the design. LC filter was used to purify the output signal from harmonics and to obtain a pure sinusoidal. Circuit diagrams were created using Proteus Design Suite and Altium Designer programs. The design was turned into a device and final checks were made in the laboratory environment, and it was seen that the system worked smoothly, and the simulation studies and experimental results coincided. The designed product gives a stable AC voltage with 220V peak voltage and 50Hz frequency.
