Under conditions of order reduction, a nonlinear control of a bidirectional coupled-inductor Cuk converter suitable for large-signal applications is presented. The converter is accurately modeled as a second-order bilinear system and the conditions established for local controllability. The integration of converter state equations and the subsequent introduction of a linear recurrence between t...

this paper presents a control strategy for fuel cell/energy storage power generation system during voltage sag conditions. the hybrid dc power sources are connected to grid using power electronic converters include dc-dc converter and grid connected voltage source inverter. the power from hybrid power sources is controlled during voltage sag by designing of control strategy for dc-dc converter....

Prior research has largely focused on the positive side of customer experience, such as satisfaction. In contrast, this study investigates the negative side of customer experience and tests the harmful impact of consumer negative voice on firms’ stock returns. Based on a longitudinal real-world data set that matches consumer negative voice (complaint records) in the airline industry with firm s...

This article presents a self-balanced multistage DC-DC step-up converter for photovoltaic applications. The proposed converter topology is designed for unidirectional power transfer and provides a doable solution for photovoltaic applications where voltage is required to be stepped up without magnetic components (transformer-less and inductor-less). The output voltage obtained from renewable so...

In this paper the control algorithm for a novel five-phase matrix converter under balanced input voltage conditions is proposed. This algorithm is essentially based on the indirect space vector modulation. The complete algorithm, analysis and the model of the proposed matrix converter are introduced. The model has been applied for the case of inductive loads. The simulation results of input-out...

An ultra-high step-up, non-isolated DC–DC converter with a continuous input current was developed as result of this research. This converter’s architecture consists voltage multiplier cell (VMC), positive output super lift Luo (POSLLC), and quadratic boost (QBS) (also referred to cascaded topology (CBT)). Thus, the bold points topologies mentioned earlier enhance gain proposed topology. It is i...

A modified LLC-T (inductor inductor capacitor) series parallel resonant converter (SPRC) has been simulated and the performance is analyzed. The limitations of two element resonant topologies have been removed by adding a third reactive element. The output voltage is regulated using fuzzy logic controller. The simulation study indicates the superiority of fuzzy control over the conventional con...

High Output Voltage Based Multiphase Step-Up DC-DC Converter topology with voltage doubler rectifiers is presented in this paper. High output voltage is obtained due to the series combination of voltage doubler rectifiers on the secondary side of high frequency transformers. This topology is useful in the application where the output voltage is greater than the input. The two loop control strat...
