Opis:: A quasi-Z-source network is used to boost the DC bus voltage of a voltage source two-level H-bridge inverter to increase the voltage gain. With the increase in the DC bus voltage, the common mode voltage (CMV) also increases. The CMV is reduced using virtual space vector pulse width modulation (SVPWM). Due to the presence of a quasi-Z-source network, the expression of the CMV changes significantly with respect to the conventional voltage source two-level H-bridge inverter fed from a pure DC supply. In this paper, a detailed analysis of the origin of the CMV for the quasi-Z-source two-level H-bridge inverter is presented. Additionally, it is shown how the CMV is affected for a DC input supply taken from a three-phase diode bridge rectifier. The work also details the scheme for suitable placement of shoot-through time intervals required for boosting within the non-active time intervals in virtual SVPWM. The simulation and experimental results show the scheme is effective in increasing the voltage gain and reducing the CMV arising at the third harmonic of the desired output frequency by at least 33.33%.

Opis:: Synchronous self-excited generators still are and probably will be the most popular 3-phase alternators installed in inland power stations so onboard of seagoing ships. Because of fuel savings and environmental restrictions Diesel, dual-fuel and gas propulsion engines for alternators of wide-range varying revolutions drives are increasingly used. There must be efficient way of creating 3-phase voltages of desired constant parameters ensured when generator produces variable amplitudes and frequencies of voltages because of changing rotational speed. As the control method modified field oriented control widely used with squirrel cage induction machines was chosen. This control method involves decoupling of currents and control voltages to flux and torque components and keeping them in optimal (orthogonal) condition. In order to obtain proper excitation and operation of such generator several factors have to be taken into account. Nonlinear dependence of voltage generated from rotational speed of self-excited synchronous generator is one of the factors that affects initial excitation process thus specific control method while generator startup. Theoretical background of synchronous generator excitation and voltage source inverter adopted FOC control method along with experimental results obtained in laboratory test bench of 5,5 kW generator and conclusions were presented.

Opis:: W układach napędowych z tranzystorowymi falownikami napięcia występują niekorzystne zjawiska wynikające z dużych stromości napięć zasilających silnik. Aby ich uniknąć między falownik a silnik włącza się filtr bierny wygładzający przebiegi napięć i prądów silnika. Włączenie takiego filtru sinusoidalnego powoduje zmianę struktury układu i powoduje konieczność modyfikacji układu sterowania silnika i estymatorów zmiennych stanu układu. W niniejszym referacie przedstawiono układ napędowy w sterowaniu którego uwzględniono filtr sinusoidalny.
In the electric drives with voltage inverters appears disadvantageous phenomena come from high du/dt in motor supply voltage. To prevent that phenomena the passive filter is introduced between motor and inverter. Filter assure smoothed voltages and current in the electric motor. When the filter is used the structure of the system is changed so the control and estimation structure should be changed also. In the paper the modified electric drive with output LC filter is presented.

Opis:: The subject of this paper is the control possibility of the multiphase cage induction motors having number of phases greater than 3. These motors have additional properties for speed control that distinguish them from the standard 3 phase motors: operation at various sequences of supplying voltages due to the inverter control and possible operation with few open-circuited phases. For each supply sequence different no load speeds at the same frequency can be obtained. This feature extends the motor application for miscellaneous drive demands including vector or scalar control. This depends mainly on the type of the stator winding for a given number of phases, since the principle of motor operation is based on co-operation of higher harmonics of magnetic field. Examples of operation are presented for a 9-phase motor, though general approach has been discussed. This motor was fed by a voltage source inverter at field oriented control with forced currents. The mathematical model of the motor was reduced to the form incorporating all most important physical features and appropriate for the control law formulation. The operation was illustrated for various supply sequences for “healthy” motor and for the motor operating at one phase broken. The obtained results have shown that parasitic influence of harmonic fields interaction has negligible influence on motor operation with respect to the useful coupling for properly designed stator winding.

Opis:: This paper presents the design and analysis process of state feedback controllers for NPC type 3-level sine wave inverter. In order to achieve good dynamic features in a state feedback control an internal model of reference input and a feedforward path are introduced. During synthesis process of the state feedback controllers maximum permissible dynamics of voltage control in the linear range of modulation is taken into account. It is shown that initially gains of the controller and feedforward path are non-stationary and depend on the angular velocity. Stationary approximation of a non-stationary state feedback controller is presented in details. Proposed state feedback control structures for continuous voltage shaping NPC type 3-level voltage source inverter are examined in FOC PMSM drive. The novelty of the presented controller lays in a stationary approximated state feedback control structure designed in terms of maximum permissible dynamics of a voltage control system. Simulation and experimental results (at the level of 3 kW) of the designed control algorithms are included.

Opis:: This paper proposes an open switch faults detection and localization algorithm for shunt three phase active filter topology. It mainly details converter configuration and examines a simple and reliable optimized fault diagnosis method. The converter topology is based on classical three-leg active power filter topology. New fault diagnosis method is proposed, based on classical currents measurements. It includes combinatory logic to analyze and validate error signals. Hysteresis control is applied before and after fault detection, which avoids any controller reconfiguration. Simulation results obtained with Matlab/Simulink/Plecs tools prove the effectiveness of this method.

Opis:: This paper proposes an augmented speed control scheme of dual induction motors fed by a five-leg voltage source inverter (VSI) with a common/shared-leg. An additional control loop is proposed here and based on the mutual flux angle – the difference between flux angular positions of the IMs. The main purpose of this research is to minimize the energy losses in the common inverter leg by controlling the mutual flux angle, at equal angular speeds of both motors. Simulation and experimental studies were carried out and the effectiveness of the proposed control method was proven. The PLECS software package was used for the simulation tests. The laboratory prototypewas prepared for the experimental validation. All results were provided and discussed in this paper.

Opis:: This paper proposes a method for compensation of dead-time effects for a five-phase inverter. In the proposed method an additional control subsystem was added to the field-oriented control (FOC) scheme in the coordinate system mapped to the third harmonic. The additional control loop operates in the fixed, orthogonal reference frame (α − β coordinates) without the need for additional Park transformations. The purpose of this method is to minimize the dead-time effects by third harmonic injection in two modes of operation of the FOC control system: with sinusoidal supply and with trapezoidal supply. The effectiveness of the proposed control method was verified experimentally on a laboratory setup with a prototype five-phase interior permanent magnet synchronous machine (IPMSM). All experimental results were presented and discussed in the following paper.
