Now-a-days the new family of dc-dc converters based on three state switching cell and voltage multiplier cells. It present a demonstrate of some advantages and limitations of a several topologies were typically use in voltage step-up applications. The operating principle of this family has chosen the boost converter and discussed in detail. The analysis of converter can applicable in uninterrup...

In Electrical power systems in future uninterruptible power supplies or electrical vehicles may employ hybrid energy sources, such as fuel cells and super capacitors. It will be necessary to efficiently draw the energy from these two sources as well as recharge the energy storage elements by the dc bus. In this paper, a bidirectional isolated dc–dc converter controlled by phase-shift angle and ...

Underwater noise was recorded from the Wavestar wave energy converter; a full-scale hydraulic point absorber, placed on a jack-up rig on the Danish North Sea coast. Noise was recorded 25 m from the converter with an autonomous recording unit (10 Hz to 20 kHz bandwidth). Median sound pressure levels (Leq) in third-octave bands during operation of the converter were 106-109 dB re. 1 μPa in the ra...

Optimal control of a wheel loader operating in the short loading cycle is studied in order to investigate the potentials for fuel consumption reduction while maintaining acceptable production rates. The wheel loader is modeled as a system with five states and three control inputs including torque converter nonlinearities. The torque converter is modeled with no lockup enabling power transmissio...

The aim of this study is to propose a high voltage lift isolated full bridge dc-dc converter. The proposed converter consists of an isolation transformer a low turn ratio to obtain high step up voltage gain. The secondary of the transformer connected with two boosting capacitors which connects parallel when power switches switch on period and discharged in series during the switch off period. I...

Abstract: In this study, a novel, non-isolated, cascade-type, single-switch, high step-up DC/DC converter was developed for green energy systems. An integrated coupled inductor and voltage lift circuit were applied to simplify the converter structure and satisfy the requirements of high efficiency and high voltage gain ratios. In addition, the proposed structure is controllable with a single sw...

This paper is about a new dc-dc converter based on VOLTAGE MULTIPLIER CELL and MULTI STATE SWITCHING CELL. This method can be applied for all type of converters like BUK, BOOST,BUKBOOST,CUK,SEPIC &ZETA. To verify the operating principle BOOST converter is chosen. Experimental analysis is obtained from 1Kw lab prototype and the results are verified using simulation software. The output current a...

The synchronous reluctance motor (Sync-RM) is known for its higher reliability, faster dynamic response, efficiency, speed range, power density, and torque per ampere. Consequently, the scope of research into emerging Sync-RMs drive system has been extended. For different kinds mechanical electrical applications, motors are important components any machine or tool. There several types available...
