    AC track circuit
    (AIKTC, 2017-05) Bodhle, Gulrez; Shaikh, Aslam (12EE3); Ali, Mohd (13EE32); Kadri, Uzma (14DEE13)
    Track circuit is the fundamental method of train detection. The first track circuit, based on a DC technology, has been invented at the end of nineteenth. Over the years, the continuous technological development has enabled to realize track circuits in an increasingly performing way by using AC technology and modulations, but the basic principle for train detection is still the same. An alternative approach is the Axle Counter system, which uses a “check-in/check-out” logic. By comparing the result for the axles counted in a block section with the result for those counted out, it is possible to know the status of the track section (free or occupied).

    Auto selection of any available phase in a three phase supply system
    (AIKTC, 2016-05) Bodhle, Gulrez; Biya, Saad (12EE10); Khan, Mohd. Sharikh (12EE55); Shaikh, Tanveer (12EE55); Shravankumar, Dilip (12EE58)
    In today's modern world where the demand of the consumers for electricity requirement is going on day by day. To achieve this ELECTRICAL POWER SYSTEM is the heart which continuously pumps the electricity from one end to other end by means of transmission and distribution system. During this process if any of the phases of healthy phases runs out then the production process at that end gets hindered which leads to economic and productivity losses. In our project we have shown by means of electrical and electronic components how auto selection can be done. We will be showing it by means of various graphs indicating various electrical parameters. We hope that our project would be successful and it would be adopted as well in the power system component

    Embeded control of Z-Source inverter
    (AIKTC, 2015-12) Bodhle, Gulrez; Hussain, Raeen; Hahasmati, Mohsin; Yusuf, Mohammed; Shaikh, Rashid
    Traditionally Voltage Source Inverter (VSI) and Current Source Inverter (CSI) fed induction motor drives have a limited output voltage range. Conventional VSI and CSI support only current buck DC-AC power conversion and need a relatively complex modulator. The limitations of VSI and CSI are overcome by Z-source inverter. The Z-source inverter system employs a unique LC network in the DC link and a small capacitor on the AC side of the diode front end. By controlling the shoot-through duty cycle, the Z-source can produce any desired output AC voltage, even greater than the line voltage (i.e. 325V for 230V AC) regardless of the input voltage. The proposed Z-source inverter system provides ridethrough capability during voltage sags, reduces line harmonics, improves power factor and reliability, and extends the output voltage range. Analysis, simulation, and experimental results were presented to demonstrate these features. This system reduces harmonics, electromagnetic interference noise and it has low common mode noise. Index Terms: current source inverter (CSI), voltage source inverter (VSI), Z-source inverter (ZSI), electro magnetic interference (EMI)

    Extracting Maximum Power from Photovoltaic System using MPPT Techniques
    (International Journal on Recent and Innovation Trends in Computing and Communication, 2016-10) Bodhle, Gulrez
    In this paper for control of photo-voltaic power by utilization of a boost converter using Maximum Power Point Tracking (MPPT) control mechanism is presented. The MPPT is responsible for extracting the maximum possible power from the photo-voltaic and feed it to the load via the boost converter which steps up the voltage to required magnitude. The main aim will be to The main aim will be to extract maximum power from the photo-voltaic so its necessary to continuously track maximum power point of the photo-voltaic module. The MPPT basically works on an algorithm. The algorithms are usually written in m files of MATLAB and utilized in simulation.

    Incremental conductance MPPT technique and energy management based on the PV-HPCS with an enrgy storage device
    (AIKTC, 2017-05) Bodhle, Gulrez; Alam, Afzal (13EE35); Dilshad, Ahmed (13EE14); Ansari, Noor (13EE11); Ansari, Mohd. Shariq (13EE09)
    Nowadays solar energy has great importance. Because it is easily available resource for energy generation. But the only problem is efficiency of solar system. And to increase its efficiency many MPPT techniques are used. Large number of papers were published on Maximum Power Point techniques (MPPT). And therefore many techniques are available for use. These techniques differs in many aspects. Incremental conductance is one of the important technique in this system and because of its higher steady-state accuracy and environmental adaptability it is widely implemented tracked control strategy. This paper presents details of Incremental Conductance algorithm with simulation results obtained using MATLAB and SIMULINK.

    Single phase to three phase cycloconverter
    (AIKTC, 2016-05) Bodhle, Gulrez; Khan, Mohsin (13EE69); Khan, Shahrukh (12EE25); Shaikh, Ahmad (11EE39); Ansari, Mustafa (12EE07)
    This project presents a new single-phase to three-phase cycloconverter suitable for driving an induction motor. Using discrete variable frequency technique, a single-phase to three-phase modulation strategy is proposed, the output frequency of this cycloconvertor can be up to half of the input frequency. Only six naturally communicated thyristors are employed, so the resulting cycloconverter-motor drive system is cheap and compact. Software in C and assembly language has been written for real-time control. The simulation based on Matlab/Simulink is used to predict the performance for the cycloconverter and induction motor.

    Solar Thermal Power Technology
    (International Journal on Recent and Innovation Trends in Computing and Communication, 2016-12) Bodhle, Gulrez
    Generally energy is available in two forms i.e. non renewable and renewable energy sources. Several environmental issues are related with the use of conventional energy sources like coal, petroleum and natural gas and different type of advantages or benefits offered by non conventional energy sources like solar, wind and small hydro included. Solar technology from history point of view is very old i.e. from 7th century B.C. to today. But in recent years the attention is more focused on solar energy for generate electricity. Solar energy help us to reduce the use of fossil fuel. Solar technology is a pollution free technology, so this technology is called by green technology. Solar energy can be used in two ways one of which is solar photovoltaic and another one is solar thermal and this paper is based on the review of solar thermal energy.
