On the Influence of the DC-voltage on the Performance of the Active Power Filter

Nonlinear loads, such as diode and thyristor based static converters, saturated transformers, etc., are typical sources of harmonic currents. These harmonics have detrimental effects on other loads that are connected to the same power supply. An efficient and high-performance solution to significantly reduce the current harmonic distortion is the use of shunt active power filters. The voltage on the DC-side of the active filter significantly affects the filtering performance. In this paper, the influence of the DC-voltage on the harmonic compensation result is investigated. The presented results are obtained by simulation using the MATLAB – SIMULINK software.
