Hybrid series active power filter for mitigating power quality problems

2017 International Conference on Energy, Communication, Data Analytics and Soft Computing (ICECDS), 2017
This paper presents various power quality problems and its mitigation through a hybrid series active power filter. Series filters have less attention in the power quality area due to its high cost of compensation, bulky transformers etc. Even though hybrid series active power filters are used in three phase system it is less utilized in single phase ...

Assessment on apparent power indices with hybrid active power filters

2017 11th IEEE International Conference on Compatibility, Power Electronics and Power Engineering (CPE-POWERENG), 2017
This paper presents a method for assessing the quality improvement of the electric power, when compensation equipment based on hybrid active power filters is applied. Power quality indicators that allow to separate the contribution to unbalance of each harmonic and interharmonic of voltages and currents are introduced, calculated with an enhanced ...

Hybrid active power filter with modular multilevel converter

2017 Nineteenth International Middle East Power Systems Conference (MEPCON), 2017
Harmonic Currents created by nonlinear loads lower the delivered power quality and affect the lifetime of electrical equipment. In this paper, Hybrid Power Filter (HPF) based on Modular Multilevel Converter (MMC) is proposed to compensate the harmonics produced by diode converter.
