Implementation of Constant Switching Frequency Hysteresis based Current Control of Solar PV Inverter

Abstract

A steady progression towards low carbon, clean energy technologies strengthens the worldwide power sector. The increasing proportion of these alternative energy sources in the world’s energy mix is accelerated by the aggressive renewable energy objectives established by various nations. The urgency of alternative options, like Solar PV, which is elevated to the pioneering renewable technologies over the decade. As a stable power electronic interface for solar PV system, inverter control requires more focused research for reliable power conversion. This research introduces a novel technique for inverter hysteresis current control at constant switching frequency. Power quality is guaranteed in this new method and this advanced control can deliver high-quality electricity to the utility grid. Through the use of this novel strategy, power conversion can be as efficient as feasible. This current control method features a quick response time and great current tracking precision. This study also involves a comparison with the existing current level PWM control approach. In order to produce quality output, this strategy has reduced total harmonic distortion and a high power factor. Effectiveness of the suggested inverter control is demonstrated by utilising the MATLAB/Simulink toolbox.
