This paper presents the input current control scheme of three-phase PWM converters to realize the unity effective power factor and the stable output dc voltage for the rectangular-waveform distribution system. The input current control is based on the discrete-time system. The authors propose the fast control scheme of the input current under the voltage saturation of the PWM converter. The effectiveness of the proposed current control scheme has been verified by experiments.

The paper discusses modelling and simulation of power circuits. Models were used to study energy exchange and develop a control system, in particular for vehicles with regenerative braking capability. SIMULINK models were used in control system design, including the selection of circuit components for feedbacks of switched mode converters. Models of the supply circuit were designed as independent blocks. These blocks can be used both, for AC induction motor drives and DC chopper drives. This structure can be used for the behavioural modelling of supply for switched-mode voltage-source traction converters.

There are sizeable pulsations in system with multi-phase electrical machines and PWM converters. They are increased under reduction winding pitch and decreased under using of multi-stage and multi-level converters and multi-phase paralleling reactors. Use of multi-stage convert-ers allows appreciably to decrease current load of capacitors in DC link.

Renewable energy is one of the most important topics for all engineers. The production of CO2 is a very finical problem for the climate of our earth. Everybody is committed to improve all opportunities to avoid the burning of exhausted raw materials.

This paper describes a hybrid fuzzy-conventional control technique of a linear induction motor. This technique, based on the use of the vector control method associated to a choice of combined analogical and fuzzy controllers, is proposed to ameliorate the dynamics of the secondary flux and the thrust force. The results of the numeric simulation are also presented and discussed

For reduction of the switching power losses developer of three-phase inverters thinks increasingly about discontinuous modulation strategies. This applies in particular for high power inverters such as for starter generator - or hybrid drive systems. The dc-link current of these discontinuous modulated voltage source inverter are analyzed in this paper. First the dc- and the rms-current of the dc-link circuit are calculated depending on the phase shift angle and the modulation factor. Afterwards the current harmonics of the dc-link circuit for a defined phase shift angle and modulation factor are determined. The calculations are verified by several circuit simulations.

Mobile robot localization is the problem of determining the pose (position and orientation) of a mobile robot under complex measurement uncertainties. The algorithm introduced here is based on the modified multiple model and exploits a soft gating of the measurements to reduce the computational requirements of the approach. The position part is based on an x and y histograms scan matching procedure, where x and y histograms are extracted directly from local occupancy grid maps using probability scalar transformation. The orientation part is based on the proposed obstacle vector transformation combined with polar histograms. Proposed algorithms are tested using a Pioneer 2DX mobile robot.

The paper deals with a front-end topology of a low power switched-mode power supply intended for a plug and play use. During its design, a special attention has been paid to a simple and cost effective solution confronted with a wide input line-voltage range (57 ÷ 3× 240)·(1 ± 0.2) VRMS and with the frequency range from 40 Hz to 65 Hz. Such extreme demands are particularly of interest in industrial applications where devices should be supplied either from the single- two- or three-phase network. In order to reduce human errors and production cost, no mechanical switches are allowed. The paper proposes a novel concept of the Flyback converter that solves the designated task with variable turns ratio of the transformer, while keeping the switching frequency constant. The implemented transformer with its control circuit enables on-line adaptation to the temporary value of input phase-voltage. As a consequence, voltage stress of implemented switching transistors is also reduced.
