“…In this work, the flying capacitor multilevel converters (FCMC) is used in the DVR configuration. In this work, multicell converters have been used for two purposes; generating a multilevel output voltage and reducing voltage stresses on the power devices [17], [18]. The topology presented in Figure 3 represents a multicellular structure with N switching cells separated from each other by (N-1) floating capacitors [19], [20].…”

Multi-level converter topologies are increasingly being used in various applications due to their high power, high voltage, and low harmonic levels in the output waveforms. These converter topologies produce different output voltage levels and have a highly modular structure. This paper proposes the design of a dynamic voltage restorer (DVR) based on multilevel topology to enhance the voltage profile and improve the power quality in the network. The DVR is an effective, fast-acting device which detects voltage sags and swells in a transmission line and inject a compensating voltage through a boost transformer. A simulation study is carried out under MATLAB/Simulate to demonstrate the performance of the proposed DVR circuit. The simulation results show improved transient response and enhanced power quality in the transmission network.

“…It has superior in harmonic compensation, smaller in size, and flexible in application. However, pure APFs configurations require either high voltage rated converter [14,15] or an isolating transformer [10,16] which slow down its application from large-scale. The HAPF came in to the field since 2003 [17] to over-come APFs limitation and to lower its investment [18].…”

Single-phase active impedance hybrid active power filter is design to mitigate harmonic and reactive caused by the ever-increasing nonlinear loads. Nonlinear loads have been increased in residential and commercial as well as industrial sectors. Single-phase nonlinear loads contribute a harmonics and low power factor for the power systems. Single-phase active impedance hybrid active power filter was investigated to actively adjust multiple active short circuits. The dominant load current harmonics are compensated due to its multiple short effects over the single-tuned LC filter. At the same time, the conservative power theory (CPT) base reactive current extraction method was applied to actively regulate the reactive power. The amount of the fundamental filter reactive current obtained from CPT determines the reactive power compensation. The results were analyzed and presented in collaboration with the MATLAB/Simulink environment and TMS320F28335 board. The active impedance and CPT based control achieved a harmonic compensation (from 65.96% to 3.20%) and power factor correction from 0.85 to 0.95. Therefore, the active impedance hybrid active power filter can be taken as a good candidate for harmonic and reactive compensation with extending the conventional hybrid active power filter (HAPF) into multiple active tuned filters. It has potential practical benefit to avoid regular field retuning the passive filter in the industry. Moreover, it can also apply for PQ compensation using the existing PPF.

“…The performance of passive LC filters depends on system impedance, series/parallel resonance, and aging effect [15,16], and they are unsuitable for variable reactive power [17]. The pure shunt APF configurations require a high-voltage-rated inverter or a multilevel inverter to withstand the loading effects [18] [19]. On the other hand, pure series APF needs an isolating transformer with sufficient line current carrying capability [12,20].…”

This article presents a single‐phase hybrid active power filter (1pSHAPF) containing a small rated active power filter connected in series with a single‐tuned inductive‐capacitive (LC) passive filter. Single‐phase nonlinear loads are increasing alarmingly in the distribution system. This is because the devices are gaining attraction for applications in information technology, emerging electric vehicle technology, and interfacing for power grids. However, nonlinear loads are common source of harmonics and contribute unpleasant conditions for the power systems. In the proposed control, a single‐phase hybrid active power filter was actively adjusted to form multiple active short circuits for characteristic harmonic. Load harmonic current easily diverted into filter path and harmonic voltages eliminated from the bus due to the active short circuit formed at the bus. The LC passive filter blocked 70% of the maximum fundamental bus voltage. This allows us to use lower DC‐link voltage hence reduces switching loss and investment for inverters. The detailed design procedures and their realization on TMS320F28335 DSP are analyzed and presented using PSIM and MATLAB/Simulink environments. The performances of the proposed controller are evaluated using diode rectifiers with resistance‐capacitance (RC) and resistance‐inductance (RL) loads. The results showed good harmonic voltage damping, current harmonic reduction (from 60.86 to 9.4%), and power factor correction. Therefore, the proposed controller can be taken as a solution to extend the hybrid active power filter (HAPF) tuned into multiple harmonic frequencies. This research has a practical benefit for power quality (PQ) compensation in the case of a single‐phase smart grid. © 2019 Institute of Electrical Engineers of Japan.
