“…They additionally must compensate for numerous disturbances in practice, such as voltage fluctuations and load changes [33]- [36]. They must hence be properly controlled to implement functions like power factor correction, predictive control, harmonic filtering, grid stability enhancement, and others [37]- [53], [107]. These functions, also summarized in Fig.…”

Within a power converter, multiple currents are usually measured for control, protection, and/or monitoring. They are therefore important sources of information, which must unquestionably be measured accurately to maintain continuous and reliable operation of the power converter. Accurate current measurement has however become tougher with the introduction of wide band-gap (WBG) devices with switching frequency tending towards the Megahertz (MHz) range. Because of that, the installed current sensors must have a significantly widened bandwidth. Moreover, they must be nonintrusive and compact, in order not to degrade fast switching characteristics and high power density of the WBG converter. Presently, these features are not collectively obtainable from existing commercial current sensors. Consequently, many new current sensing techniques have surfaced in the literature for usage with the more demanding MHz power converter. These new techniques, some classical techniques, and their hybrid integrations are now reviewed, after overviewing functionalities made possible by current sensors in a power converter. Last but importantly, some future developmental trends aimed at matching MHz current sensors with MHz power converters are described, before concluding the paper.

“…It is observed that all predictive controllers find a solution at around 0.01 seconds, which is well below the sample time (0.05 seconds). It should be noted that due to the distributed structure of the predictive scheme, the number of optimization variables is fixed (see Equation (14) and Equation ( 15)). Fig.…”

“…The compensation of imbalance can be achieved using active power filters (APFs) to compensate unbalanced currents or unbalanced voltages at specific points of the MG [14], [15]. However, APFs are not attractive in MGs since they constitute additional hardware and higher costs.…”

“…Later, other control methods were developed [32][33][34], in particular, the use of Fourier transform [35][36][37], direct methods [38][39][40], and artificial neural networks [41][42][43][44][45]. This development also concerned the APF topology, and the converters used [46][47][48][49][50]. An active power filter (APF) is also called an active power line conditioner (APLC), instantaneous reactive power compensator (IRPC), or active power quality conditioner (APQC).…”

Distortions of current and voltage waveforms from a sinusoidal shape are, not only a source of technical problems, but also have serious economic effects. Their occurrence is related to the common use of loads with nonlinear current-voltage characteristics. These are both high-power loads (most often power electronic switching devices supplying high-power drives), but also widely used low-power loads (power supplies, chargers, energy-saving light sources). The best way to eliminate these distortions is to use active power filters. The cost of these devices is relatively high. Therefore, scientists all over the world are conducting research aimed at developing techniques for the proper placement of these devices, in order to minimize their investment costs. The best solution to this problem is to use optimization techniques. This paper compares the methods and criteria used by the authors of publications dealing with this topic. The summary also indicates a possible direction for further work.
