This paper presents the design and implementation of a power converter for an autonomous wind induction generator (IG) feeding an isolated load through the PWM-based novel soft-switching interleaved boost converter. The output voltage and frequency of the wind IG is inherently variable due to random fluctuation of wind-speed variation. The interleaved boost converter composed of two shunted ele...

The increasing demand for hybrid energy systems based on renewable sources has enabled the new dimension multi-input converter (MIC). Various topologies have been introduced over last decade. However, most of these several drawbacks in terms design complexity or efficiency. Therefore, this research aims to introduce a DC-DC applications. proposed is able hybridize different such as solar PV arr...

The present study was undertaken to investigate the effects of varying frequency patterns (FPs) of words on the productive acquisition of a young EFL learner in a home setting. Target words were presented to the learner using games and role plays. They were subsequently traced for their frequencies in input and output. Eighteen immediate tests and delayed tests were administered to measure the ...

The interleaved buck converter with high conversion rati...

High boost DC/DC voltage conversion is always indispensable in a power electronic interface of certain battery-powered electrical equipment. However, a conventional boost converter works for a wide duty cycle for such high voltage gain, which increases power consumption and has low reliability problems. In order to solve this issue, a new battery-powered combined boost converter with an interle...

In this paper, a 0.18-V input three-stage charge pump circuit applying forward body bias is proposed for energy harvesting applications. In the developed charge pump, all the MOSFETs are forward body biased by using the inter-stage/output voltages. By applying the proposed charge pump as the startup in the boost converter, the kick-up input voltage of the boost converter is reduced to 0.18 V. T...

This paper focuses on the study of DC-to-DC converters, which are suitable for low-voltage high-power applications. The output voltages generated by renewable energy sources such as photovoltaic arrays and fuel cell stacks are generally low and required to be increased to high voltage levels. Development of DC-to-DC converters, which provide high step-up voltage conversion ratios with high effi...

A state feedback control method for an interleaved boost power converter is designed, which, in turn, can achieve interleaved current sharing among parallel-connected converters. The state feedback control in the continuous time domain is derived using the pole placement technique and linear quadratic optimal method. The load estimator is designed by deriving a full-order state observer to ensu...
