Impulse Commutated Frequency Modulated Soft-Switching Current-fed Converters
Impulse Commutated Frequency Modulated Soft-Switching Current-fed Converters
Abstract
Impulse Commutated Current-fed is a 'Unidirectional' class of current-fed converters attaining soft-switching, zero current commutation, and voltage clamping of semiconductor devices through a high- frequency resonant tank. It is a simple, easy, and cost effective way of solving the traditional turn-off voltage spike across the devices. The important point to note is that this is not a resonant converter because the design is done such that the resonance takes place during a short period,.ie. the overlap period of the devices when turn-off procedure of a pair of devices is about to start. Therefore, it offers benefits of peak and circulating current limitations as compared to the conventional resonant converters. Device rms and average currents also reduce with the load current and therefore, does not compromise on partial load efficiency. Voltage gain characteristics are immune to load variation. However, voltage regulation against source voltage variation is attained through frequency modulation. A detailed and systematic analysis and design procedure is developed to design the resonant tank to achieve the desired attributes. These converters are suitable for solar photo voltaic and fuel cell applications or in general mainly low voltage high current applications.

Design & Development of Feed Systems for Low Earth Orbit Satellites Tracking by Joint Collaboration of IIST and NRSC Hyderabad
Design & Development of Feed Systems for Low Earth Orbit Satellites Tracking by Joint Collaboration of IIST and NRSC Hyderabad
Abstract
LEO satellites which are also referred as Sun Synchronous Earth Observing Satellites which orbit very fast regarding to ground station and collect the imagery data of earth.
To collect imagery data from these satellites at ground station, generally X-Band transmission is employed with suitable modulation scheme employed in the satellite. As these are orbiting at lower orbital height, Auto Tracking schemes like Monopulse Tracking, need to be employed in ground station antennas for tracking of these satellites to receive data without any loss. However, such systems are limited in terms of bandwidth and hence, available data rates. Therefore, the need for high data rates and large bandwidth sense a thrust to include higher frequency Ka-band with the existing dual frequency band systems.
However, with the upcoming of such earth observation satellites, large ground station antenna systems are required to communicate with the satellite. These antennas require high gain, with multiband operating capability and being very narrow beam width for higher frequencies, high pointing accuracy is required.
Hence, in order to cater stringent pointing
accuracy and multiband capability ,single feed catering multiband with auto tracking mechanism is required to determine the accurate location of the satellite to facilitate ease of data reception.
In this talk, starting from different tracking mechanisms, elaborating on single element tracking scheme, various ways of designing tracking feed to cater for multiband data reception, their advantage and disadvantages along with design

Feed Antenna for Low Earth Orbit Satellites Tracking: An Overview and Recent Activities in NRSC Hyderabad
Feed Antenna for Low Earth Orbit Satellites Tracking: An Overview and Recent Activities in NRSC Hyderabad
Abstract
Remote Sensing satellites are mainly LEO satellites which orbit very fast regarding to ground station. So, tracking of these satellites is very critical in order to collect imagery data from the satellite without any loss. By using orbital Keplerian parameters, the trajectory of the LEO satellite can be estimated. This method is called Program Tracking Method. As accuracy of this metod is not superior, different alternative methods of tracking have been adopted since the early days of Radar and Satellite Tracking.
Most popular, sophisticated and efficient method ofvarious tracking is Monopulse. A Monopulse Tracking Techniqueis very accurate, free from mechanical vibration, gives high SNR and has been adopted in most of the ground stations for tracking LEO satellites.
In this talk, starting from basics, different modes of Monopulse Tracking Feed, their advantages and disadvantages along with design challenges will be highlighted.

Substrate Integrated Waveguides : Early Development and Recent Trends
Substrate Integrated Waveguides : Early Development and Recent Trends
Abstract
In high-frequency applications, microstrip devices are not efficient, and because wavelength at high frequencies is small, microstrip device manufacturing requires very tight tolerances. At high frequencies waveguide based devices are preferred; however, their manufacturing process is difficult.Substrate Integrated Waveguide (SIW) has emerged as an attractive alternative which incorporates non-planar waveguide structures in the planar substrate by the use of rows of metallic vias implementing the sidewall of the waveguide based circuits in a planar substrate. SIW is a new form of transmission line used as an interconnection in high-speed circuits, filters, directional couplers, and antennas. In this talk, staring from the basics of SIW, recent works of SIW based circuits and antennas contributed by my research group would be highlighted.

IEEE Antennas and Propagation Chapter Seminar Lecture on High Power Microwave Mode Converters
IEEE Antennas and Propagation Chapter Seminar Lecture on High Power Microwave Mode Converters
Abstract
High Power sources like vircator and relativistic magnetron are used to generate very high power levels (in Gwatt range) for a variety of applications like remote mine clearing, directed energy applications etc. The power produced by these sources usually consists of the TM01 mode. The problem with TM01 mode is that the radiation pattern of this mode is not directional with a null present along the direction of propagation. This is not conducive for achieving high antenna gain. On the other hand the TE11 mode does have a directional radiation pattern and is preferred for achieving high antenna gain. In this talk we describe some new designs for converting from TM01 to TE11 mode.

Antenna Systems for 21st Century Satellite Communication Payloads (under IEEE Distinguished Lecturer Seminar Talk)
Abstract
21 st century has so far seen several new satellite services such as local-channel broadcast for Direct Broadcast Satellite service (DBS), high capacity K/Ka-band personal communication satellite (PCS) service, hosted payloads, mobile satellite services using very large deploy-able reflectors, high power hybrid satellites etc. It is important to integrate more capabilities into the satellite while reducing the cost. Antenna sub-system design, mechanical packaging on the spacecraft, and RF performance become very critical for these satellites. This talk will cover recent developments in the areas of antenna systems for FSS, BSS, PCS, and MSS satellite communications. It includes advanced antenna system designs for contoured beams, multiple beams, and re-configurable beams, Multiple Beam Antenna (MBA) concepts with its advantages, recent advances in feed technology and reflector technology, introduction to remote sensing antennas, advanced high power test methods for satellite payloads, and future trends in satellite antenna systems.
