This paper presents UPQC, a Unified Power Quality Conditioner. this technique offers circuitous power quality pay of the voltage and conjointly the provision current. Latest studies have recommended that the UPQC has high efficiency and higher power quality. this may be accustomed management the flexibility flow inside the transmission by dominant...

The project is to designed detect vehicle movement on highways to switch ON only a block of street lights ahead of the vehicle, and to switch OFF the behind lights to save energy. During night all the lights on the highway remain ON for the vehicles, but lots of energy is wasted when there is no vehicle his movement. This proposed system provides a...

Human tracking is implemented on a video sequence, which involves the analysis of the presence, size, shape and position of human beings. Human tracking is generally used in applications like video surveillance, crowd monitoring. Videos are series of images, called frames, which are displayed in faster frequency, such that human eyes will not be ab...

The usage of Electric Vehicles is increasing rapidly, we need to decrease the time required for charging. Therefore there is a demand to built High rated Charging Stations (CS) to reduce drivers Range Anxiety. Neutral Point Clamped (NPC) Converter containing Charging Station have benefits, but this converter has problem of unbalanced power. To over...

The conventional Unified Power Flow Controller (UPFC) exists two back 2 back inverters and more complex zigzag transformers for isolation and accomplishment high power & voltage ratings. To overcome these difficulties, two zigzag transformers are wholly eliminated in this place two cascaded multi-level inverters are presented. The single configurat...

: Imperativeness increase of network to compelled districts is connected with specific and modest. Enabled examination abuse age manageable power.Test displays execution an unbiased miniaturized scale matrix topology relying upon a lone. Miniaturized scale matrix structure is empowered with various maintainable power sources to be explicit breeze a...

Agriculture is the most important back bone of India. Now a day's farmers are reduced because of various problems like water problem, real estate, technology etc. Here our proposed system is to make use of existing technology to improve the farming percentage, gardening and nursery in a smart, effective and accurate method. Our proposed design is a...

This paper presents an efficient topology and fuzzy control strategy for hybrid system which utilizes multiple types of power sources such as photovoltaic systems, rechargeable batteries and fuel cells. The proposed topology works only with four switching elements controlled by fuzzy controller for simultaneously performing multiple tasks such as c...

Renewable Energy Sources are increasingly integrated at the distribution level due to increase in load demand which utilize power electronic converters. A novel active clamping zero voltage switching SVM controlled three-phase grid connected inverter is proposed in this paper. The inverter can realize zero voltage switching (ZVS) operation for all...

In modern power system consists of wide range of electrical, electronic and power electronic equipment in commercial and industrial applications. Since most of the electronic equipment’s are nonlinear in nature these will induce harmonics in the system, which affect the sensitive loads to be fed from the system. These problems are partially sol...

In this paper, a ZVS-PWM three-phase current-fed push–pull dc–dc converter is proposed. When compared to single-phase topologies, the three-phase dc–dc conversion increases the power density, uses the magnetic core of the transformer more efficiently, reduces the stress on switches, and requires smaller filters since the frequency for its design is...

A four level static compensator integrating two 2 level converters, supplying/absorbing reactive power to/from the grid, is reported in our earlier paper. Reduced component count, simpler layout for switches, and smaller DC link capacitor values are the attractive features of the proposed topology over the diode clamped and cascaded multilevel conv...

With a sprit use of non conventional energy generating sources, photovoltaic (PV) array installations are constitute increasingly engaged in so many applications, like distributed energy generation and stand-alone systems, grid connected systems to improve the power quality features. A specific and simple control method is suggested for compensatin...

Nowadays, the non renewable energy sources are used compared with renewable energy sources, because day by day the non renewable energy sources are reduces. The main energy supplier of the worldwide economy is fossil fuel. This however has led to many problems such as global warming and air pollution. Therefore, with regard to the worldwide trend o...

Brushless dc motors have only decades of history. They have been gaining attention from various industrial and household appliance manufacturers because of its high efficiency, high power density and low maintenance cost, silent operation, compact form, and reliability. The presented Hybrid Active Power filter is able to operate in variable load co...

A active power filter implemented with multiples of single phase full bridge voltage-source inverters connected in series (known as cascaded H-bridge multilevel inverter or binary multilevel VSI) is presented and analyzed in this paper. The proposed active power filter is aimed to compensate harmonics, reactive power, and improvement of power facto...

Grid connected solar system uses to have converters Circuits followed by two levels: A DC/DC boosters and PWM Inverter. This combination of converters leads to decrement of Quality and efficiency of electric power, In this paper the author Propose a single phase 13-level photo voltaic (PV) inverter for Grid connected solar system with A novel pulse...

There are some existing single stage converters in which the bus and output voltages are not controlled, A SVPWM fed converter is achieved to control the intermediate voltage, output voltage may be regulated and the power factor correction may be achieved. The circuit is formed by integrating a boost PFC converter with a two switch clamped forward...

Nonlinear loads such as traditional diode/thyristor rectifiers with R, L, C loads generate harmonic and reactive current, which leads to poor power factor, low energy efficiency, and harmful disturbance to other appliances. Active Power Filters (APFs) are one of the viable solutions to eliminate the power line harmonic/reactive currents generated b...
