This paper proposes the virtual flux based direct power control for Vienna rectifier. No need for the input voltage sensors, the current regulation loop and PWM voltage modulation block along with the active and reactive power decoupling are some of the salient advantages of this method that make it suitable for controlling the conventional active rectifiers. However, due to the three-level nat...

In this paper, Vienna rectifier and Z Source Inverter (ZSI) based Wind Power Conversion System (WPCS) has been proposed with less number of switches to provide high quality power to off grid system. The three phase full bridge converter has six switches for the conversion of AC-DC and also need separate DC-DC boost converter to boost the DC voltage. In the proposed WPCS, three Phase Vienna rect...

The Vienna rectifier can produce three voltage levels, however only the connection to neutral-point is fully controllable using bidirectional switches. When not imposed in a phase-leg, polarity of pulses generated depends on diode that conducting which defined by current direction. As result, go opposite direction what demanded controller, and becomes distorted. This be mitigated injecting part...

46 Abstract -Efficient control of power has popularized the use of power electronic components and the challenges in their implementation have forced the developers to develop auxiliaries and schemes for their trouble free operation and control but the very approach is making the power system and equipment extensive and complex. Thus has arisen a need to obtain a device that is robust, highly e...

This paper provides a comparative evaluation of different topologies Vienna rectifiers. rectifier is used for AC-DC conversion and has reduced number switches. The PWM-based control mechanism the reduces losses capacitor better efficiency. There type rectifiers this evaluates topologies. Three-phase converters are available in major advantage three-level power electronic converter reduction swi...

This article is a study on the analysis of harmonics reductions and load voltage control for Vienna Rectifier (VR) with help of the Triplen Harmonic Injection (THJ) and the proportional integral controller (PIC). The sinusoidal PWM is the easiest modulation technique for AC-DC rectifiers to comprehend; however, it is not capable of entirely using the accessible DC bus source voltage. In order t...
