“…The necessity of this controller indicates a serious drawback of VSC‐based APFs in the deterioration of total harmonic distortion (THD) of the network voltage. Using cascaded H‐bridge multilevel converter by Zhou et al has led to a transformerless medium‐voltage APF. Because of the limited switching frequency (typically below 1 KHz) of high‐power solid‐state devices (GTO/IGCT), multiple synchronous/stationary reference frame current controllers has been presented.…”

Summary This article establishes a new parallel hybrid active power filter that is elaborated on the joint operation of voltage and current source converters. The idea is in fact combining a voltage source converter (VSC) and a current source converter (CSC) in parallel to form a hybrid scheme that aggregates the benefits of both converters and does not have drawbacks of each one of them. It is conceptually discussed that when low‐frequency components in the reference current are conducted to the CSC and high‐frequency components are devoted to the VSC, then significant reductions can be obtained in the sizes of the hybrid compensator's elements. However, the merit of the proposed scheme is dependent on separation frequency. The idea is then supported by mathematical descriptions and next validated by a series numerical simulation in Matlab/Simulink environment. The performance of the proposed hybrid scheme is successfully examined in a typical distribution network and also compared with a CSC and/or VSC alone.

“…The effect of applying E during 1/2 period and zero during the rest of the period is the same as that of applying 2E/3 during the first 1/2 period and E/3 during the second 1/2 period. However, the configuration which is applied on the inverter has an influence on the current of flying capacitor (11), thus an influence on the voltage. Table I gives the variations of flying capacitors corresponding to each configuration.…”

“…Pure active power filters are more expensive than hybrid active power filters, but they assume more functions than passive or hybrid active filters [10]. Multilevel inverters are more and more used for active power filter [11], [12], and the use of multicell inverters increases [13]. The use of multicell inverters, which benefit from several advantages such as low switching ripple, few conduction losses, and small dV/dt, is a way to improve the bandwidth of active power filters [14].…”

“…Multilevel topologies are effective in high voltage applications as they provide high output voltages with same voltage rating of individual device and eliminates the need of transformers [19][20][21][22]. In addition, they are able to generate output voltages and currents with low harmonic distortion as well as to reduce voltage stress across switching devices.…”

In this paper, backstepping control for three-level four-leg shunt active power filter (SAPF) system is proposed. The adopted filtering topology requires both a three-dimensional space vector modulation (3DSVM) for controlling the three-level four-leg inverter as well as DC voltage and filter currents control. The regulation of the DC voltage and filter currents is accomplished by backstepping controllers. The voltage-balancing control of two split DC capacitors of the three-level four-leg SAPF is achieved using three-level three-dimensional space vector modulation equipped by a balancing strategy based on the effective use of the redundant switching states of the inverter voltage vectors. The simulation results show the effectiveness of the proposed filtering system in terms of the compensation of the harmonics and the zero sequence current and the operation at unity power factor.
