Opis:
The problems connected to developing inductive power transfer IPT systems in aspects of high efficiency and suppression of electromagnetic field (EMF) emission are discussed. It is shown how important it is to compensate for large leakage impedance of IPT coils (air transformer) to improve efficiency of high power transfer. Such compensation circuits operating with resonant frequencies at soft switching conditions additionally allow for reduction of switching losses in power semiconductor devices of converters. The consideration has been illustrated and verified by experimental results measured on two different test stands (50 kW with planar coils and with two 12 kW receiver coils) built in a laboratory of the Łukasiewicz Research Network – Electrotechnical Institute.

Opis:
The article presents physicochemical, thermal and spectroscopic properties of two different glass systems: TeO2-GeO2-PbO-PbF2- BaO-Nb2O5-LaF3 and SiO2-Al2O3-Sb2O3, co-doped with Yb3+/Tm3+ ions. Blue upconversion luminescence at a wavelength of 478 nm corresponding to the thulium 1G43H6 transition was observed under 976 nm pump radiation in both of the co-doped glasses. This indicated the existence of efficient Yb3+ ⇥ Tm3+ energy transfer via three-photon absorption mechanism. Thermal and optical results substantiate the claim for practical applicability of the manufactured glasses in design of optical fiber sources.

Opis:
In the paper a bi-directional power electronic interface based on an inductive coupled contactless energy transfer system for plug-in vehicles with Vehicle-to-Grid (V2G) capability is presented. To minimize the total losses of the system, a series resonant compensation circuit is applied assuring Near to Zero-Current Switching (N2ZCS) condition for insulated-gate bipolar transistors. The analytical expression of the dc voltage and current gains as well as energy transfer efficiency is given and discussed. The system uses modified FPGA based integral control method adjusting resonant frequency and guarantees very fast and stable operation. Simulation and experimental results illustrating properties of the developed 40-60kHz switching frequency operated 15kW laboratory prototype are presented.
