This article presents the basic theory of operation of proportional resonant controllers, and introduces a possible implementation for the control of single-phase voltage source inverters. The corresponding software is given for Simulink and C++ code and is made available for. . The study evaluates the performance of an inverter control in a single-phase grid-linked PV scheme, focusing on addressing issues like transient response, voltage overshoot, harmonics and steady-state error. This paper. . The primary objective is to develop an efficient and reliable inverter system that ensures maximum power extraction from the solar PV array and seamless integration with the grid. Switching pulses for the conventional H-bridge inverter are generated, and the output total harmonic distortion. . This paper provides a design procedure of single-phase inverter with LC filter and the inverter load current is regulated by Proportional-resonant controller.
