  • IECON - Fictive Axis Emulator-based state feedback vector current control for single-Phase voltage source converters
    IECON 2013 - 39th Annual Conference of the IEEE Industrial Electronics Society, 2013
    Co-Authors: Michail Vasiladiotis, Alfred Rufer
    Abstract:

    This paper presents a vector current control method tailored for single-Phase voltage source converters. In order to imitate the behavior of a three-Phase system, the Fictive Axis Emulation (FAE) concept is employed. The latter is able to synthesize the rotating reference frame components of a single-Phase Quantity. The multivariable state feedback controller is designed based on the concept of complex transfer functions. A desired dynamic behavior and practical axis decoupling are achieved by proper pole placement. The controller exhibits robustness over a wide range of parameter variations. Simulation as well as experimental studies verify the described concepts.

  • Instantaneous single-Phase system power demonstration using virtual two Phase theory
    2008 International School on Nonsinusoidal Currents and Compensation, 2008
    Co-Authors: B. Dobrucky, M. Pokorny, Mariana Benova
    Abstract:

    The paper deals with the virtual approach and application of orthogonal transform theory, used for ordinary single-Phase system to its transformation into equivalent two-axes system. It is well known that the analysis of multiPhase systems can be more simple using the Park/Clarke transform into two-axis stationary (alpha, beta) or rotary (d, q) reference frame. The above transform can be used for electrical machines as well as for power electronic systems. The projection of time state-space vector for any Quantity of symmetrical three-Phase system in Gauss complex plane (alpha + jbeta) shows out six-side symmetry of vector Quantity trajectory. Then, analysis of such system can be focused on the interval equal to 1/6 of the time period only. It is clear that when using similar transform of single-Phase Quantity into equivalent two-axes orthogonal system it will be possible to use all advantages as in three-Phase transformed system with respect of 4-side symmetry instead of 6-side of previous case. Analysis in such orthogonal coordinates system will then be identical to the three-Phase one under Park/Clarke transform, including determination of instantaneous reactive power. The presented method creates a virtual two-Phase system from the original singlePhase system by adding a new fictitious Phase. The new thought is based on the idea that ordinary singlePhase Quantity can be complemented by virtual fictitious Phase so that both of them will together create orthogonal system, as is usual in three-Phase systems. Application of above-mentioned theory makes it possible to use complex methods of analysis as instantaneous reactive power method. Both, the active and reactive powers can be determined by this way. Practical application of the method is outlined for the case of active and reactive power determination for single-Phase power active filter, unified power flow controller, and dynamic voltage restorer, Fig.1 [14], [15], [17] - [19].

  • Speeding-Up of Dynamic States for Single-Phase Power Active Filter
    2006 12th International Power Electronics and Motion Control Conference, 2006
    Co-Authors: B. Dobrucky, Rastislav Pavlanin, Viktor Bobek, Igor Gerek
    Abstract:

    The paper deals with the new method of analysis of single-Phase power electronic systems. Using a new particular transform theory the ordinary single-Phase system can be transformed into equivalent two-axes orthogonal one. The new original thought is based on the idea that ordinary single-Phase Quantity can be complemented by fictitious second Phase so that both of them will create orthogonal and ortho-normal system, as is usual in three-Phase systems. Application of above theory makes it possible to use complex methods of analysis as instantaneous reactive power method, which have not been usable for single-Phase systems so far. Both, the active and reactive powers can be determined by this way. Practical application of the method is outlined for the case of reference current determination for single-Phase power active filter. Three different ways of reference current determination are discussed results. The paper shows some examples of the experimental verification results, which proved an extremely fast response of the single-Phase active filter with control algorithm, based on the described method
