Central Manufacturing Technology Institute, Bangalore, India was using Raytheon precision laser driller/welder which was manufactured around twenty years back. The laser system was manufactured using analog controllers. The company is finding difficulty in procuring analog components which was used twenty years back, during maintenance and feature up gradation. Analog controllers are non-expansible...
Aircraft applications demand high reliability and high power density while aiming to achieve simplicity in operation, increased fuel efficiency and reduced costs of operation and environmental impact. Fighter aircraft especially, must have high manoeuvrability and must be able to handle huge thrust as compared to passenger aircrafts. This paper deals with the development of an all electric actuator...
This paper presents the redesigning the distributed analog controller used in Raytheon Laser Precision welder/driller system which is around thirty years old. Main difficulty faced is that, the components associated with distributed analog controller of laser system are now obsolete. Some of the disadvantages of analog controllers are that they are bulky, expensive and complex design making troubleshooting...
A high conversion ratio dc-dc converter suitable for renewable energy applications has been investigated and presented here. A high-boost dc-dc converter is designed with high voltage conversion ratio for fuel cell or photovoltaic systems. The proposed system consists of a current-fed half bride at the input side, an active-clamp circuit and an output voltage-doubler with three stages of boosting...
