A novel enhanced connection of AC/AC powertrain for HEV - modelling and simulation results

The paper deals with a novel enhanced connection of AC/AC powertrain for Hybrid Electric Vehicles (HEV). The substantial contribution of such a connection is the absence of 4QC auxiliary converter needed for autonomous and hybrid operational modes and its compensation by power-lesser 0x5 matrix converter. The main advantages of a simplified connection are, beside smaller auxiliary converter sizing, also possible better efficiency of the HEV powertrain. So, powertrain operation in autonomous traction accu-battery modes uses direct 0x5 configuration of traction 3x5 MxC matrix converter, and in hybrid modes of Internal Combustion Engine (ICE) and accu-battery uses besides traction 3x5 MxC matrix converter the auxiliary 0x5 matrix converter. Modeling and simulation using Matlab-Simulink environment of traction powertrain configuration in autonomous modes are presented in the paper as well as all simulation experiment result

New possibilities of power electronic structures using SiC technology

This paper is dedicated to the recent unprecedented boom of SiC electronic technology. The contribution deals with brief survey of those properties. In particular, the differences (both good and bad) between SiC electronics technology and well-known silicon VLSI technology are highlighted. Projected performance benefits of SiC electronics are given for several large-scale applications on the end of the contribution. The basic properties of SiC material have been discussed already on the beginning of 80’s, also at our university [1]

Design, Modelling and simulation of two-phase twostage electronic system with orthogonal output for supplying of two-phase asm

This paper deals with the two-stage two-phase electronic systems with orthogonal output voltages and currents - DC/AC/AC. Design of two-stage DC/AC/AC high frequency converter with two-phase orthogonal output using single-phase matrix converter is also introduced. Output voltages of them are strongly nonharmonic ones, so they must be pulse-modulated due to requested nearly sinusoidal currents with low total harmonic distortion. Simulation experiment results of matrix converter for both steady and transient states for IM motors are given in the paper, also experimental verification under R-L load, so far. The simulation results confirm a very good time-waveform of the phase current and the system seems to be suitable for low-cost application in automotive/aerospace industries and application with high frequency voltage sources

This paper deals with the investigation of DCand AC energy transfer transients for ultra deep wells. Twotransfer energy approaches are described: DC and AC threephase systems transmission via power cable. The transientscould be switch on, switch off for no load, rated load andover load conditions. The simulations analysis of bothsystems are described and compared. The losses arecalculated and discussed

Using Z-transform for solution of steady state and transient state in single-phase voltage inverter system

The novel approach of analysis and modelling of power single-phase voltage source inverter with resistive - inductive load is introduced in the paper. The mathematical description of this system is using state space model with Z-transform method and series. Created impulse switching functions are used as exciting functions of this state space model. It makes possible to obtain the state variables in steady state and transient state in time domain using simulation model

Analysis and simulation of LCTLC resonant inverter with multifunction output

The paper deals with design analysis and simulation of power resonant inverter with integrated LCLC filter and VF transformer (LCTLC). The filter provides sinusoidal output voltage for sensitive loads with harmonic distortion roughly 5% in the whole range of the load (0-100%). The LCTLC filter is supplied from either single-phase voltage inverter in full- or half- bridge connection, or from simple DC/DC buck converter. The output can be considered as simply controlled AC HF power generator (power supply) or DC rectified output (DC power supply), or/and as AC LF source with variable frequency
