Inversional and rotational isomerization mecha'!lisms in N2H2 and CH2NH have been studied by an ab initio procedure including in the solute hamiltonian the reaction potential of a solvent mo. delled as a dielectric continuum. The basic computed quantity is a solution free energy parametrically dependent on the solute internal coordinates. The solvent effect, mainly related to the hybridization ...

New control circuits and algorithms are frequently proposed to control the impedance (Z) source inverter in efficient way with added benefits. As a result, several modified control techniques have been proposed in recent years. Although these techniques are clearly superior to the simple boost control method which was initially proposed along with the Z-source inverter (ZSI), little or conf...

In this paper, a fuzzy-logic-based energy management system and multi-port quasi-z-source converter that utilizes hybrid renewable sources are proposed. The ensures each source module can be used individually by employing fuzzy logic to define the power modes. This approach also helps prevent switching losses resulting from extra of modules. addition, proposed does not have mathematical model, ...

In this paper, an Enhanced Z-source inverter is proposed. Compared to the traditional Z-source inverter, it can obtain high voltage conversion factor with a short shootthrough duration, and can decrease Z-source capacitor voltage stress significantly. In order to identify its inherent character, the transient modeling of continuous conduction mode (CCM) in dc side is presented. Through the deta...

This paper is devoted to in-detail demonstrationand description of the overall functionality and deailed processes in every component quasi-z-source voltage inverter. Expressions for currents voltages on all elements circuit standard "shoot-trough" modes are provided. These ratios demonstrate one main technological advantages topology: which possibility reduction capacitor that forms quasi-z-ci...
