Abstract
The paper presents possibilities of compensation of general single-phase load connected to the three-phase grid. The compensation is to ensure a symmetrical and pure active load of the three-phase grid. It is documented that after the proposed compensation it is possible to draw symmetrical and pure active current from all phases. A set of multi-level voltage converters is considered as a compensation device. The paper presents a way of determining the reference currents for the converter in its two branches and proposes a method of controlling the converter so that the active power from the grid is equal to the active load of the load. This methodology is documented by the results of a series of simulations for static and dynamic modes of the system.
