In this project presents a new non conventional energy source based bidirectional dc/dc converter for transfer the power in both directions. The nonconventional source of solar energy with Maximum Power Point Tracking is used to avoid the demand of electric power, which is inexhaustible and non pollution .The maximum power point traction is the combination of switch mode converter and Controlle...

In this paper wind and solar based stand-alone hybrid energy system is presented for the remote area power system applications. The wind, solar, battery, fuel cell and dump load (i.e., aqua-electrolyzer) are connected to the common dc bus. An ac load is connected to dc bus through a pulse width modulation (PWM) based inverter. Ac voltage at load bus can be maintained at rated value by regulatin...

The dissertation presents a generalized average-current-mode control technique (GACMC), which is an extension of the average-current-mode control (ACMC) for single-phase ac-dc boost converters with power factor correction (PFC). Traditional ACMC is generalized in a sense that it offers improved performance in the form of significant reduction of the current control loop bandwidth requirement fo...

Solar DC pump system is easy to install and operates full automatically without watching. Solar DC pump needs less solar panels to run than the AC pump. A simulation model is necessary for the manufacturer to assess the performance of solar pump controller. Solar DC Pump consists of solar PV Modules, solar DC controller, and submersible DC pump. Solar cells have nonlinear I-V characteristics, e...

This paper will focus on the definition of the main performance characteristics that must have a converter power cell to fit the above mentioned application range. Starting with the establishment of the relevant trade-off parameters, in terms of power handling capability, input and output operational voltage ranges (both in nominal and emergency conditions), conducted emissions, bus capacitor a...

Deicing of overhead transmission lines are necessary to prevent damage to the transmission system and outages. In this paper, a modular multilevel DC de-icer (M2D2) is introduced, based on the structure of modular multilevel converter (MMC) with full-bridge submodules. The M2D2 exhibits a lot of salient features: high modularity, scalability, compactness, high efficiency, wide DC voltage range,...

Author Affiliation: Institute for Power, Electronics and Telecommunications Engineering, Faculty of Engineering, University of Novi Sad, Novi Sad, Yugoslavia. Abstract: The aim of this letter is to present a universal power quality conditioning system (UPQS) named after unified power quality conditioner (UPQC), which is extended by adding a shunt active filter at the load side. Its main purpose...

This paper explains a new proposal for the placement, integration, and control of unified power quality conditioner (UPQC) in distributed generation (DG)-based grid connected/autonomous micro grid/micro generation (μG) system has been presented here along with fuzzy logic controller. Here we using fuzzy logic controller instead of using other controllers. The DG converters (with storage) and th...

The current power sector is dealing with the poor power quality issues and the reason behind this poor power quality is voltage fluctuations, harmonics, transients and reactive power demands and these problems arises due to changing trend of our demand. Nowadays in our demand the share of power from power electronic devices has increase a lot and also coupling of grids to wind farms and solar f...
