“…But the quality of the voltage profile determined by Pulse Width Modulation (PWM) employed on the switches. 4 PWM is a method control current flow in the switch, which impacts the output voltage, can be controlled efficiently. Sinusoidal PWM is a method, which decides the ON and OFF period of the switches by comparing sinusoidal reference and triangular carrier.…”

The Harmonics control of any inverters can be decided by the PWM incorporated for the switches. In recent years the carrier and reference modification based research is going on the inverter field. This paper suggests that the alteration of carriers and references of the three phase voltage source inverter enhance the ability to decrease the harmonic content.This enhanced realization deals with the carrier and reference modification arrangement for three phase voltage source inverter through amalgamating the boosted reference and random triangular carrier. The boosted reference is the addition of sine reference with injection of 1/3rd of reference amplitude (3fs) in the middle portion of the reference wave. i.e., [Formula: see text] to [Formula: see text] and [Formula: see text] to [Formula: see text] . The proposed PWM scheme use two carriers, one is Triangle wave and another one is inverted Triangle wave. The process of selecting the winning carrier among the two triangle carriers is purely based on the LFSR technique. The spectral quality of the induction motor drives has improved by the random carriers. The simulation and experimental values are proving the validity of the PWM method. The PWMs are generated by using parallel processing enabled FPGA processor.

“…The MPPT method automatically finds the current or voltage at which a PV array should work to extract the maximum output power under given temperature and irradiance conditions [20]. The P&O algorithm is very common and suitable for practical applications [19,21,22]. This algorithm is based on the system perturbation by the decreasing or increasing duty cycle and the results are seen on PV output panel.…”

“…Conventional method P&O may give error in results that is, when solar irradiance is increased, the algorithm moves in the direction of high power and it fixes the operating point, which is not maximum power point (MPP) [22]. The FLC method is applied in this work in pursuit of improving the control performance of MPP through simulation and modelling based fuzzy logic rule [8].…”

This paper describes the work performed on a single phase 9-level cascaded H-Bridge multilevel inverter (CHB-MLI) for photovoltaic (PV) power generation, using two methods of maximum power point tracking (MPPT)-namely fuzzy logic controller (FLC) and perturbation & observation (P&O). The MPPT scheme is used to extract maximum power from solar PV cells. PV cell temperature and solar irradiation are input quantities and the two used methods estimate the optimum duty cycle to ensure DC-DC boost converter maximum output. This paper also compares the results obtained by the work performed on CHB-MLI with DC-DC boost converter using FLC based MPPT controller to that of results obtained with the conventional P&O method. The fuzzy logic controller works with imprecise inputs, it does not need an accurate mathematical model and it can handle nonlinearity well. Besides, fuzzy is more robust as compared to the conventional non-linear controller. The genetic algorithm (GA) based Selective Harmonic Elimination (SHE) technique is also applied to CHB-MLI for the elimination of harmonics from the output voltage. In the work reported in this paper on PV inverter making use of the Fuzzy MPPT technique, the obtained total harmonic distortion (THD) of the output voltage without filter circuit and with filter circuit are within IEEE standard 519.
