Algorithms for processing polarization-rich optical imaging data
(Indian Institute of Science, 2005-04-13)
This work mainly focuses on signal processing issues related to continuous-wave, polarization-based direct imaging schemes. Here, we present a mathematical framework to analyze the performance of the Polarization Difference ...
Modeling, Analysis And Control Of Single-Phase And Three-Phase PWM Rectifiers
(2009-06-16)
Pulse width modulation (PWM) rectifiers are extensively used in battery charger, regulated dc voltage source, UPS systems, ac line conditioner and motor drives. The conventional control schemes for these rectifiers require ...
A New Family Of Soft Transition DC-DC Converters
(2009-09-10)
Switched mode power supplies (SMPS) have found wide spread acceptance in all power processing applications. The design demand is moving towards higher power densities. For reduction in size and weight, it is imperative to ...
Soft Switched Multi-Phase Tapped-Boost Converter And Its Control
(2009-08-04)
Boost dc-to-dc converters have very good source interface properties. The input inductor makes the source current smooth and hence these converters provide very good EMI performance. On account of this good property, the ...
