Potential of an improved energy efficiency in the chassis
Abstract In this paper, an approach is presented to determine the losses of the different components in the chassis system. An enhanced two-track model is extended by sub-models to simulate losses and efficiencies. These sub-models are describing the loss behavior, which is compared to the state of art. The energy saving potential of each component is analyzed by optimizing the package of ax…

Performance evaluation of multi-stage open-loop impedance pump
Abstract Background: Impedance pump is a simple valveless pumping mechanism, which transports fluid through the mismatch of impedance in the system. Mismatch in impedance occurs when an asymmetrical periodic excitation is exerted on the elastic tube. Periodic asymmetrical excitation will then produce a unidirectional flow. Considering a multi-stage system with a single and constant power so…

Abstract In this study, bidirectional dc–dc (BDC) converterbased dynamic voltage restorer (DVR) is proposed for compensation of severe voltage sag/swell problems in a medium voltage system. Among these problems, voltage swells provoke the voltage rise at dc-link capacitor of DVR. This undesirable situation may explode the dc-link capacitors and switches, and cause high-power losses. In DVR …

Dynamic performance of wind turbine conversion system using PMSG-based wind s…
Abstract This paper presents an experimental investigation of a small-scale wind turbine conversion system (WTCS), using wind power simulator based on a permanent magnet type synchronous generator (PMSG) which is directly coupled to a servomotor to emulate the WTCS. The wind power simulator is either speed or torque controlled in which propose a “wind shaft”, to verify the dynamic and sta…

Development of an optical fiber-based interferometer for strain measurements …
Abstract In this paper, an extrinsic Fabry–Perot interferometer (EFPI) has been demonstrated for strain measurements. A monochromatic light source with a wavelength of 1310 nm is propagated into a single-mode fiber and then passed through the sensing arm. Approximately, 4 % of the beam is reflected off at the fiber end generating the “reference signal”, while the rest is next transmitte…

Comparison performance between sliding mode control and nonlinear control, ap…
Abstract A squirrel cage induction motor has been the workhorse in industry for variable speed applications in a wide power range that covers from fractional horsepower to multi megawatts. But the control and estimation of ac drives in general are considerably more complex than those of dc drives. The advent of vector control techniques has partially solved induction motor control problems. H…

Analytical calculation method for the non-linear characteristic of ferrite-co…
Abstract Magnetic devices are essential components in the field of power electronics. Exploiting the non-linear behavior of inductors and transformers offers the great merit of increasing the performance of switch mode power supplies. For instance, the light-load efficiency of a buck voltage regulator can be improved by using a non-linear inductor with stepped air gap. Moreover, non-linear ch…
