“…The harmonics attenuation of the LCL-SR filter is very high as a consequence it reduces the number of components used for harmonics attenuation and reduces the cost Osório et al (2020). To provide a gate pulse to the switches of the inverter PWM Liserre et al (2001), Shanono et al (2019), Blaabjerg et al (2006) techniques have been used. In the PWM modulation technique, the output power quality is good because it gives less distortion in the output waveform Rosso et al (2019) .…”

Power quality challenges arise when photovoltaic (PV) systems are integrated into power networks. This research work examines the control and mathematical design of an LCL-SR filter for power quality improvement in PV-based sustainable energy systems to meet this difficulty. Power quality may be improved via LCL filter in grid-connected systems. A non-linear load-connected PV system incorporates a variety of power electronics controllers, including as an MPPT controller, battery controller, and inverter current controller, which introduce harmonics into the grid. A passive filter, LCL-SR, is suggested for PV applications that interact with voltage source inverters and the utility grid or electric load to reduce harmonics. A detailed mathematical modeling is presented to design an LCL-SR filter, and its performance is evaluated under different load conditions in terms of THD and efficiency. LCL-SR filter has 4.32% THD but in the case of LCL filter with parallel R is less THD, which is 3.61%. In terms of efficiency and THD LCL-SR is best among all compared filters which have THD is 4.32% along with an efficiency is 75.95%. The results are compared without a filter, and different configurations of LCL-SR are simulated to show the effectiveness of the proposed filter for PV & residential applications.

“…Converters with less harmonic-order elimination capability tend to have larger-sized filter components, hence increasing its physical size, weight and cost [21]. This issue is addressed by employing special modulation technique or new converter topology or both to eliminate the lower harmonics, hence, leaving behind only the higher-order ones that require a smaller-sized filter component [4,16,21].…”

Performance comparison of series and parallel damped LCL filters using 5-level voltage source converter

The high harmonic content produced by conventional converters has resulted in the increased system size and cost, due to the need for large-sized low-order harmonic passive filters and cooling system requirement. Given that, multilevel inverters and special modulation techniques were developed to suppress or eliminate the low-frequency harmonics and the left behind high-order ones are eliminated using a high-frequency small-sized filter. Hence, this paper designs and compares the total harmonic distortion (THD) and efficiency values of three set of filters, namely LCL filter, LCL with series and parallel resistance on a novel five-level multilevel voltage source inverter topology. The novelty lies with the proposed inverter, which, apart from using a single direct current source, it can extend it elimination capability beyond the normal five level using the concept of multiple switching per step and an optimised selective harmonic elimination pulse width modulation. The converter can eliminate eleven lower-order odd nontriplen harmonics, hence making the 37th harmonic at 1.85 kHz to be the first dominant harmonic. At 2-kW loading, two of the filters have THD below 5%, therefore satisfying the IEEE 519 standard. The parallel resistance damped filter (LCL-P-R) has less THD value but poor efficiency due to the resistance introduced into the circuit. The study was carried out using PSIM and MATLAB software.

This paper presents a five-level inverter based on the phase-disposition pulse width modulation (PD-PWM) technique for renewable energy applications. The conventional cascaded H-bridge (CHB) five-level inverter structure is reproduced, and an LC filter is designed to get optimum results from the inverter output. Two batteries are used as renewable energy sources to investigate the performance of the designed inverter. The system can provide 220 volts and 50 Hz AC supply with a 6.9 kW power supply to the load/grid. The designed output is compared with filter and without filter circuit. It provides sinusoidal voltage and current output with a very low total harmonic distortion (THD) of 2.75% which is compliant with IEEE 519 standards. MATLAB/Simulink software tool is used for the entire design. The inverter’s output is graphically represented, and discussed various parameters like switching frequency, THD, modulation index, and rated voltage.
