Abstract. The unbalanced voltage conditions deteriorate the performance of the harmonic detection of active power filter (APF). To address this problem, a complex LMS based method is proposed in this paper. A complex Least Mean Squares (LMS) is designed for phase-tracking. DSPOC principle is utilized to adjust the estimate of synchronous frequency. Then, the proposed method is employed to improve the harmonic detection of APF. The effectiveness of the method is confirmed through simulation results.

The parallel iteration method for frequency estimation based on trigonometric decomposition is presented. First, the multi-frequency signal can be expressed in a matrix form based on the trigonometric decomposition, which implies a possibility to solve the nonlinear mapping functions of frequency estimation by a parallel iteration procedure. Then, frequency estimation with the minimized square errors is achieved by using the gradient-descent method in the parallel iteration procedure, which can effectively restrain the interferences from harmonics and noise. Finally, the workflow is shown, and the efficiency of the proposed method was demonstrated through computer simulations and experiments.

“…Since three-phase diode rectifiers are widely used in industry, such as adjustable speed drives and dc power supplies (Thasananutariya and Chatratana, 2009;Chen and Luo, 2001;Grbovic et al, 2001), the harmonics generated by the diode rectifier in the line current is a main concern in power electronics. To eliminate the harmonic current generated by this type of harmonic source, the shunt Active Power Filter (APF) or series APF has been an effective solution (Corasaniti et al, 2009;Singh and Solanki, 2009;Lavopa et al, 2009;Rahmani et al, 2010;Vodyakho and Mi, 2009;Salmeron and Litran, 2010;Bhattacharya and Chakraborty, 2011). However, the rating of APF is normally small because of its partial power processing property.…”

This study describes a novel method in improving the input current total harmonic distortion as well as power factor of a three-phase diode rectifier circuit. In this method, three bidirectional switches comprising MOSFET and four diodes are used across the three-phase supply and load. In a three-phase rectifier only two diodes conduct at any given time. As a result, the current in the third phase is zero. But in this method, the bidirectional switch corresponding to the third phase is turned ON. The closing of bidirectional switches provides an alternate path for the input current to flow. Once the input voltage crosses zero-voltage axes, the corresponding switch will be triggered. The fuzzy logic based control method is used to generate the triggering pulse for the bidirectional switches. The conduction angle of bidirectional switch is adjusted to make the output power constant and at the rated value for converter operation above and below its rated power. The performances of DC motor drive as well as Induction motor drive are evaluated with this method. The analysis, simulation and experimental results of three phase rectifier are also presented in this study.
