In recent years, multilevel technology has become an effective and practical solution for moderate and high voltage application field. In all multilevel technology, cascade multilevel inverters have become the major circuits used in power quality conditioners. Evidently,the voltage balancing problem of DC capacitors of cascade inverters is a key problem to the power quality conditioners. This paper...

Parallel active power filter is one of the most effective solutions to compensate the current harmonics and to enhance the power quality in industrial application. Regularly, the PAPF is controlled as a current source with the amplitude similar to the harmonics component of load current. This paper proposes a novel voltage-mode control in which the power inverter is controlled as a voltage source...
Active power filter (APF) is one of the most effective solutions to compensate the current harmonics and to enhance the power quality in industrial application. Control is one of the key elements to their performance. This paper proposes a generalized control approach for APF, which provides a systematical way not only to analysis the regular control schemes but also develop new control schemes. Based...

According to digital signal processing technology, the digital algorithm for the instantaneous reactive power theory is discussed. The real-time detection approach of harmonic current based on it is proposed and the corresponding detection system including DSP is configured. The simulation and the experiment investigations aiming at the detection system are done to show the performance of the detection...
