Design and Development of Off-grid Power Inverter

Year: 2025

Type: article

Abstract: In this paper, an off-grid power inverter for the application of the photovoltaic (PV) powergeneration system is proposed.The PV power-generation system used by an inverter supplies a utility sinusoidal source.To obtain the maximum power of the PV power-generation system and the low total harmonic distortion of the off-grid power inverter, a linear approximation control algorithm method and a sinusoidal pulse width modulation (SPWM) method are adopted.On the basis of an advanced control technology to obtain the optimum dynamic regulations of the offgrid power inverter, a peripheral interface controller and a SPWM microcontroller are used.Finally, to verify its feasibility, a prototype of the off-grid power inverter is built.Theoretical and experimental results are presented to demonstrate the performance of the off-grid inverter.
