Presents the introductory welcome message from the conference proceedings. May include the conference officers' congratulations to all involved with the conference event and publication of the proceedings record.
Modern systems are becoming ever more complex and, thus, the possibility of failures in their operation is also growing. The complexity makes it practically impossible to make the hardware and software error-free without the special effort invested in the design process. Recently, a design methodology with the objective to avoid unacceptable risk of physical injury or of damage to the health of people,...
The paper presents an overview of various steps required for solving the problem of designing electric drives for traction applications. The design problem is solved as an optimization problem with multiple objectives subject to various constraints governed by physical characteristics and limitations of materials and specific parts used for the assembly of electric motors and power converters, international...
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...
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...
This paper proposes a controller design of a distributed power source inverter to be useful both under the stand alone mode and the grid-connected mode to compensate the current harmonics from the local nonlinear load. The PR based multi-loop controller is used to improve the system dynamic performance and to compensate the output voltage or grid current harmonics depending on the operation modes,...

This paper mainly deals with an EDLC based-electric scooter and its unique super-rapid pulse charging...
In recent years, the wireless EV chargers have been spotlighted as convenient, safe, and clean apparatus. In this paper, proposed has been a newly developed large-gap wireless power transfer EV charger which can communicate control signal to a power feeding unit from a power receiving unit without any additional communication equipment. The wireless power transfer (WPT) system with a single-ended...
To have more effective fault ride through operation for the power conditioner of the photovoltaic system, the detection of the imbalanced condition is important factor. In this paper, new detection method by using the complex number algebra in real time control system is shown. Very fast detection of the imbalanced condition is verified by simulations and experiments.
This paper deals with a cost effective wireless EV battery charger which integrates the simplest quasi-resonant soft switching pulse modulated inverter with a newly developed SiC-MOSFET. In the first place, the operating principle of a wireless EV charger using a class-E single-ended inverter which is cost-effective for affordable price and simple is described. This type of wireless resonant EV charger...
The paper focuses on optimal current quality (minimal Total Harmonic Distortion — THD) for a single-phase three-level inverter modulation. Previous works addressed optimal THD problem in frequency domain accounting for a limited number of harmonics. The uniqueness of this work is in its time-domain formulation of minimal current THD problem, which facilitates optimization accounting for all harmonics...
Paper deals with analysis and modeling of a new type of single-phase supplied single leg LC matrix converter (SLLC MxC) with two phase outputs. Its schematic arrangement consists of one-leg half-bridge matrix converter, network with a neutral point, LC filters, switched capacitor and passive or active load. As the harmonic analysis of the voltage of both phases gives a very high value of total harmonic...
This paper deals with basic research in the field of the wireless power transfer (WPT) systems and normalization of the electromagnetic field exposure of those systems.

The simulation model of shielding plates is reconfigurable...
This paper addresses calculation of current Total Harmonic Distortion (THD) for a three-phase two-level PWM inverter with an LCL-filter. Analytical approach introduced in late 1980s for a two-level inverter with inductance dominated load is generalized accounting for the smoothing effect of an LCL-filter. Though the obtained closed-form analytical solutions initially assume (infinitely) large ratio...
When a converter changes into the discontinuous mode, a ringing starts across the semiconductors. This is caused by the necessary voltage step across them and the necessity to charge the parasitic capacitors of the devices. To reduce this swinging, another strongly coupled winding is applied to the magnetic device of the converter. By shunting this winding, when the active switch and the passive switch...
