Harmonic elimination by SPWM and THIPWM techniques applied in photovoltaic inverters

With advances in solid-state power electronic devices, control techniques (PWM) have been devised to obtain high dynamics responses from a multilevel conditioning converter-Photovoltaic. This work discusses the advantages and drawbacks of two different PWM techniques, sinusoidal (SPWM) technique Third harmonic injection (THIPWM) technique. These methods are compared by discussing their ease implementation analyzing output spectra various voltage total distortion (THD). The focus this paper is simulation study single-phase inverter, three phases, levels inverter for application photovoltaic. Firstly, single phase modeled with inductive load waveforms observed. Secondly, leading industrial performances drives synchronous, especially, if high-power quality requested.
