This paper describes a realization of a bipolar current source developed by the paper's authors. The source is intended for use in galvanic and other industrial plants, where a pulse-reverse current supply (with the desired shape in time) is required. A prototype of the device, which provides the outcome current intensity up to ± 50 A, has been constructed. The hardware of the source consists o...

An interleaved high step-up converter topology based on the coupled inductor (CI) and built-in transformer (BIT) is proposed in this study to provide voltage gain efficiency with a low number of power electronic components for renewable energy applications. The increased by both turns’ ratio CI BIT, so there no need extend duty obtain gain. much more flexible than those only either or BIT. More...

In this paper, a new high efficiency, high step-up, non-isolated, interleaved DC-DC converter for renewable energy applications is presented. In the suggested topology, two modified step-up KY converters are interleaved to obtain a high conversion ratio without the use of coupled inductors. In comparison with the conventional interleaved DC-DC converters such as boost, buck-boost, SEPIC, ZETA a...

In this paper, a full analysis is presented on digital-to-analog conversion for pulse amplitude modulated (PAM) systems. By analyzing the cyclostationary nature of pulse-amplitude modulation (PAM) systems, two methods of quantization are proposed – fixed and adaptive. Examples of this quantization analysis are provided for the reverse link transmitter chain in a cdma2000 system, and for the bas...

in this article our objective is to obtain steady state characteristics of shunt, series, and separately excited dc motors coupled with a centrifugal water pump supplied through a step-up, step-down, and cuk converter from photovoltaic generator. we assume that there are no storage batteries and, of course, the system must operate on maximum utilization i.e. maximum water must be pumped. it is ...

Reliability and energy consumption are two of the main constraints in wireless sensor networks (WSNs). In this paper, a novel energy efficient and high speed error control scheme is introduced that is based on the Redundant Residue Number System (RRNS) allowing real-time application of WSNs. The proposed approach employs a new 3-moduli set {22n+1, 22n+1 − 1, 2n − 1} and an efficient reverse con...
