Design And Implementation Of Non-Isolated Half Bridge DC-DC Bidirectional Converter Using Fuzzy Logic
Increasing energy demand and environment constraint of fossil fuels renewable energy is encouraged. Considering increase in energy demand bidirectional converter is widely used. the study aims to design and implement a Half bridge non isolated bidirectional DC to DC converter using fuzzy logic. In the presence of dc mains the converter operates as buck converter and charges the battery. When the dc mains fail, the converter operates as boost converter and the battery feeds the load. In both the modes the power switches are controlled by PWM technique and the PWM pulses are generated by application of fuzzy logic controller. The proposed converter with controller is implemented and simulated in MATLAB and the design is validated.

An Earthquake detector using Arduino board and highly sensitive accelerometer that can detect minute vibrations is presented in this paper. The components are able to provide immediate alert and helps to take preventive measures against earthquakes accordingly.
An Dynamic Voltage Regulator For HVDC System On Low Power DC Line With Series Active Power Filter And Reducing Repulsion To The Transmitting Station
Harmonics in HVDC power systems, which are caused by highly non-linear devices, affect its performance. Therefore, the main concern of power engineers in power system design and operation have been controlling and eliminating such repulsion. In respect of this, HVDC power system repulsion analysis is, therefore, imperative in power system planning, control and operation. It is worthy of note that, different alternatives of filter design should be considered before making final decision on filter Configuration. In this paper the reduction of harmonics in the HVDC power transmission system by implementing the active power filter. Also the power factor is increased drastically by reducing the current harmonics in the load side. The solar PV output can be presented and analyzed with help of boost converter in order to proof that the solar output voltage can be increased by the boost converter. The series active power filter appears to be a viable solution for eliminating repulsion currents and current transient condition. Shunt active power filter compensates current by injecting equal voltage compensation is created by nonlinear loads
So1ar Powered Unmanned Surface Vehic1e for Survei11ance
The unmanned surface vehic1e is more popu1ar because of its 1ow cost, f1exibi1ity and a1so it he1ps to reduce the danger to human beings. In this artic1e we describe measurement of environmenta1 monitoring app1ications using integrated sensors and a1so water ph. 1eve1, enemy monitoring using wire1ess camera. So1ar pane1 is used power the mode1. It can f1oat on the water and can a1so run on the surface of earth using servo motor. Using ESP8266 node MCU can send the data to c1oud.
Analysis and Detection of Ovarian Cyst Using Soft Computing Technique in MATLAB
Cyst and polycystic ovary syndrome is a disorder is a normal phenomenon that affect woman in the perlite age. The most important thing is that PCOS. PCOS syndrome is mainly found in women aging from 12 year to 60 year. In our project, we will be going to use more neighbour counter, water shade method, active counter models, Gaussian filtering and binary filtering method are going to be used in this paper to detect the size, shape and border of the ovarian cyst from echography images. In order to analyse the efficiency of segmentation and application developed in MATLAB software is proposed.
