Abstract:  This paper transcribes the evolving scenario of Digital control method used in Power Electronics Systems (PES) using DSP controller for the implementation of the power electronic circuits. DC-DC converters topologies are widely used in PES for various voltage conversions. In DC-DC power converters Digital control is becoming more and more common because of the low cost, high performance Digital Signal Processing (DSP) controller. Power electronic peripherals such as analog to digital (A/D) converters and pulse width modulator (PWM) are integrated on DSP chip.

Keywords:  Digital control, Boost converter , DSP controller, closed loop control .

Abstract:  In MANET route optimization is the basic requirement to improve the QOS of the network. QOS may be well explained in terms of optimize distance, reliable energy, time response etc. To improve the quality of service we use different changes in MANET protocols, its parameter, routing algorithm etc. In the proposed work we are also improving the QOS by modifying the routing algorithm. The proposed routing algorithm is inspired from the genetic approach. The proposed work is implemented using the FIGA(Fuzzy Improved Genetic Algorithm)  As  in  initializing  phase  we  will  select  the shortest  path  and  one  alternative  aggregative path.  The shortest path selection always returns the congestion over the network. Instead of using the shortest path we will select a genetic inspired path. In this work, the selection of the next cross over child path will be identified based on cyclic fuzzy logic. The whole process will optimize the routing algorithm to improve the QOS. The proposed work is implemented on MATLAB 7.1 environment.
