In the single-phase grid-connected inverter systems the high quality Total Harmonic Distortion (THD) factor must always be considered. In cases, when the supplying voltage is reduced, the output voltage can still be assured constant in the limited range by using the over-modulation strategy that also enables better utilization of dc bus. Unfortunately, this operation incurs high order harmonics' force...
Paper deals with LCLC converter with DC output. Both current and voltage sourced output rectifiers are considered. The performance investigation is focused on the nominal and overload operation conditions. Several differences are discovered during transient and steady — state analysis. Most significant is the existence of "zero-voltage interval" (ZVI) at the parallel resonant tank of the...

This paper presents the design of Unscented Kalman Filter (UKF) for estimation of state space variables of permanent magnet synchronous machine (PMSM). The UKF is shown together with the field oriented speed control. At first, the position and the speed of PMSM are measured, and UKF is used only for a load torque estimation. It is indicated how differences in sampling time of the speed and the current...
The paper brings second part of an analysis and synthesis of servo-drives with integral low-pass disturbance observer (DO) filters. The loop established by extending a stabilizing PD-controller by a binomial noise attenuation filter and by a disturbance reconstruction and compensation is devoted to the position control. The dominant loop dynamics represented by an inertial mass is approximated by...
According to WHO, around a billion people with disabilities live in the world. About one third of these people are people with mobility or movements impairments. For most of these people, high-precision hand prostheses such as bebeonics or touchebonus are very expensive. Prosthetics controlled from the nervous system directly exist only as prototypes. All of the above devices provide only visual feedback...
The paper presents the analysis of the performances of an Outer Rotor Synchronous Reluctance Machine as potential candidate for direct-driven low speed industrial application. The influence of slot/pole combination, as well as the number of flux-barriers was investigated in order to arrive to a topology suitable for the targeted application. The proposed machine has the highest average torque and...
This paper deals with performances of the two cylindrical permanent magnet synchronous motors (PMSM) identical from the point of view of geometrical dimensions but with different stator windings and PM materials. Motor A has fractional slot concentrated winding and rotor with ferrite magnets and motor B has distributed windings and rotor with NdFeB magnets. Parameters and performances of both motors...
Testing of electric vehicle drives in real traffic conditions is relatively expensive and complicated task. Therefore new laboratory methods, enabling testing and special parameters of electric drives measurement "like in real traffic" are in the looking for. One of most effective methods is based on HIL (Hardware In the Loop) which represents combination of simulation methods and measurements...

There are many publications that emphasize the advantages of C- and E-Core Flux-Switching-PM-Machines, which apply less magnet material than the conventional Flux-Switching-PM-Machine. However, most researches only focus on low-power applications beneath 1 kW. This paper investigates the performance of Flux-Switching-PM-Machines in a speed range between 1000 min−1 and 3000 min−1 at a 300 W and at...
This paper presents a simple methodology for calculation of the Permanent Magnet Synchronous Machine (PMSM) efficiency map. The presented method requires only the machine nameplate data and allows to a system designer to estimate the efficiency for different operating conditions, such as a different driving cycle in traction applications. The method has been experimentally verified for both large...
