Abstract

Modern trends place a significant deal of attention on power quality and stability in distribution networks. The main cause of the PQ issue is the nonlinear loads, which result in current harmonics. It causes noise on the regulating and control circuit, which leads to incorrect operation of such equipment, and it causes considerable interaction with communications circuits along with AC Power line. This is one of the main problems with electricity quality. Using HPF in conjunction with the SSTL inverter, this power quality trouble can be reduced. HPFs can be connected straight to grid without the need for matching transformers by using smaller rating inverters and LC filters as part of their HPF design. Conversely, employing two converters results in a greater quantity of switches. The system is dependable, easy to use, and cost-effective when Transformer-less HPF with SSTL inverter is used to improve harmonic compensations in addition to harmonic compensation.
