Due to the potential benefits resulting from the use of more than the conventional three phases in transmission, some interest has also grown in the area of multi-phase (phase order more than three) machines in recent years. Multi-phase loads particularly in the form of inverter fed induction motor drives suited to high power and specialized applications, are receiving growing attention in the ...

This paper presents four types of time domain control techniques for generation of real time compensating current with a view to the problem of source current harmonics caused by non-linear loads in three phase three wire shunt active filters. All the techniques are analyzed mathematically and simulation results are compared in terms of compensation performance with multi parameter under steady...

Shunt Active Power Filters (SAPFs) represent the most important and widely used filter in industrial purposes due to the fact that, they not only eliminate the harmonic current with a neglected amount of active fundamental current supplied to compensate system losses, but also they are suitable for a wide range of power ratings. One of the key issues for a proper implementation of an active fil...

in this paper, a novel control method for photovoltaic converter connection to the national gridis presented, so in addition to the injection control by solar arrays to the grid, this method cancompensate reactive power and harmonics in the load current. the system will be connected inparallel between the grid and load. the proposed system supplies all load power consumption(including active po...

This paper proposes a new adaptive filter for wind generators that combines instantaneous reactive power compensation technology and current prediction controller, and therefore this system is characterized by low harmonic distortion, high power factor, and small DC-link voltage variations during load disturbances. The performance of the system was first simulated using MATLAB/Simulink, and the...

-A new control method for single-phase shunt active power filter (APF) is proposed. It integrates the DC bus voltage control and active power filter command current generation, according to the periodicity of source current and energy balance concept. The instantaneous harmonic compensation and linear DC bus voltage control are achieved, without complicated and involved control logic, by using ...

-A three-phase hybrid series power filter is constituted by a series active filter and a passive filter connected in parallel with the load. The control strategy is based on the “dual formulation of the electric power vectorial theory”. The proposed algorithm eliminates the current harmonics of supply. It also improves the power factor and harmonic compensation features of the associated passiv...

In distributed generation systems, power quality is one of the main concerns during short-term unbalanced grid voltage faults. However, for most common three-phase three-wire grid-connected inverter-based there may be a tradeoff between oscillations and current harmonics fault ride-through control, which has crucial impact on installed inverters different applications. this article, modified in...
