In solar PV systems, harmonics are primarily introduced by inverters, variable-speed motors, LED lighting, EV chargers, and certain electronic equipment. Excessive harmonics can cause overheating, reduced inverter efficiency, nuisance tripping, transformer stress, and poor. . Harmonics in solar inverters emerge primarily from the pulse width modulation (PWM) switching process, the core control method used to generate AC waveforms. Inverters are mainly used to convert direct current into alternating current & act as interface between renewable energy & grid. Inverter-based technologies and various non-linear loads are used in power plants which generate harmonics in system. . PV inverters use semiconductor devices to transform the DC power into controlled AC power by using Pulse Width Modulation (PWM) switching. PWM switching is the most efficient way to generate AC power, allowing for flexible control of the output magnitude and frequency.
