An accurately regulated improved multiple output Forward dc-dc converter is proposed. In this topology, each output has its own feedback control circuit for output regulation, that controls the appropriate synchronous rectifiers in the pertinent output stage, to eliminate cross-regulation between outputs. Steady state analysis as well as state space(More)
Multi-level voltage source inverters offer several advantages such as a better output voltage with reduced total harmonic distortion (THD), reduction of voltage ratings of the power semiconductor switching devices and also the reduced electro-magnetic interference problems etc. This paper presents the application of simplified space vector modulation (SVM)(More)
Shunt Active Power Filter (SAPF), when used with non linear loads, provides an elegant solution to reactive power compensation as well as harmonic mitigation leading to improvement in power quality. The present study deals with fuzzy logic control for SAPF. Its superiority over PI type of controller is demonstrated through simulation results.
The main objective of this paper is to develop a power conditioning system, which can be used to extract the variable solar DC power from sun and convert it into AC power to feed a 3-phase AC load effectively. This paper presented the simulation results of Photovoltaic (PV) power conditioning system for three phase AC loads. The conditioner consists of a(More)
The objective of the present research was to develop a novel pH triggered nanoemulsified in-situ gel (NE-ISG) for ophthalmic delivery of fluconazole (FLZ) to enhance the permeation and residence time of the formulation, by overcoming the limitations associated with protective ocular barriers. Pseudoternary phase diagrams were constructed using capmul MCM(More)
Dc-dc Zeta converter is a buck-boost type of converter, which yields dc output voltage with same polarity that of the input voltage. It is widely used in various domestic and industrial applications. For good voltage regulation, fast dynamic response, and stable operation of this converter, a feedback control design is necessary. Therefore, in this paper,(More)
Space vector modulation is a widely used pulse width modulation technique for variable speed drive application.

This paper proposes a sensorless vector control scheme for induction motor to operate at low speed. The integrator in the reference model of the rotor flux based Model Reference Adaptive System (MRAS) have the problems of dc drift and dead time. A new integration algorithm is developed for rotor flux based MRAS to reduce the effects of integrator.(More)
It is observed that many researchers are working in developing new breed of dc-dc converters for various applications. For analysis and controller design, physical system is needed to be modeled into either transfer function form or state space form. However, researches are using conventional approach for obtaining transfer function from state space form.(More)
This paper presents a single-phase two-stage non-isolated converter for on-board plug-in hybrid electric vehicle battery charger. The first stage is a conventional boost converter and the second stage is a bi-directional dc-dc converter (battery-interface) having a wide range of output voltage with low component stress in both directions compared to(More)
