‎ 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, a direct ac-to-dc power converter is proposed for efficient energy harvesting from the low voltage inertial micro generators. The conventional power converters use diode bridge rectifiers and condition the micro generator outputs in two stages. Hence, they are inefficient and may not be a feasible option for very low voltage micro generators. Moreover, they are not conducive for ...

This paper presents a boost converter along with a flyback converter. The Zero Voltage Switching (ZVS) technique is used to achieve soft switching. A bidirectional boost converter is connected with an output module as a Parallel Input Serial Output configuration. The flyback converter with Voltage Doubler Rectifier (VDR) acts as an output module. This connection makes a bidirectional boost conv...

In this paper an efficient high step-up converter with a coupled- inductor with soft- switching operation is presented. The proposed topology includes a coupled-inductor boost converter for raising the voltage gain. Moreover, a simple auxiliary resonant circuit composed of an auxiliary switch, a clamping diode and a resonant tank (inductor, capacitor), is adopted in this paper. The coupled-indu...

In this paper, a high voltage gain of DC-DC converter with design and simulation are proposed using coupledinductor. The proposed converter duty ratio is 0.65, so appropriate duty ratio is considering for this design of the converter. Due do more number of switches are considers for the converter circuit will make more switching power losses but in this converter using only two switches and hav...

In this paper an efficient topology of (Single Ended Primary Inductor Converter) SEPIC/Zeta converter is proposed to interface renewable energy sources and the load. The proposed converter is obtained by the integration of the bidirectional converter and the full-bridge converter. As the output voltage of the proposed converter is not reversed this topology provides remarkable advantages than t...

This paper proposes a design of single input multiple output (SIMO) dc–dc converter. The proposed converter can generate the voltage of a low voltage input to controllable levels of boosted output voltage and it can also produce the inverted output voltage. This dc-dc converter utilizes the properties of voltage clamping and soft switching based on a coupled inductor. In this paper, the design ...
