‎ In this paper, the stand-alone photovoltaic system for cathodic protection of underground pipelines is presented. The proposed system offers continuous and automatic adjustment of the applied voltage so that the buried pipelines receive the exact current. A modified perturb and observe (P&O) algorithm for maximum power point tracking (MPPT) is used to improve dynamic and steady state performa...

In this paper, Performance of three-level integrated ac–dc converter with Hysteresis Current Control Technique is presented. The proposed converter combines with the operation of the boost power factor correction and the three-level dc–dc converter. By the implementation of Hysteresis Current controller, the switching sequence is under controlled condition and the output voltage of the proposed...

In this paper, the proposed single boost converter aims to harness more than one renewable energy (RE) input source and achieve a high voltage gain. The interleaved technique combined with multiplier (VM) cells, reduced inductor current attained transfer ratio. possesses two unidirectional ports bidirectional port that is connected battery storage. duty ratios of power interleaving switches are...

In this paper, distortion in the output envelope of AM modulated a class E RF power amplifier with a nonlinear capacitance with the grading coefficient 5 . 0 = m is analyzed. The calculation of output amplitude incorporates the influence of power loss versus dc supply voltage. Derivation of half cycle output voltage waveform is done with incorporating output amplitude as a function of dc supply...

Hybrid power systems means connection of more than one source at the input of system. To continuously deliver the power from source to load, the use of single output with single input non-isolated dc-dc converter is not that much sufficient, then for this type of systems, single output with multiple input converter proposed. It can regulate the voltage levels above or below the input voltage by...

In this paper, a three-level integrated ac–dc converter with power factor correction is presented. The proposed converter integrates the operation of the boost power factor correction and the three-level dc–dc converter. The converter is made to operate with two independent controllers—an input controller that performs power factor correction and regulates the dc bus and an output controller th...
