power amplifier circuit diagram



Circuit Description
There are many instances where a simple and reliable power amplifier is needed - rear and centre channel speakers for surround-sound, beefing up the PC speakers, low powered tweeter amplifier, etc. For those who want to build their own 'Gainclone' amplifier, this will certainly do the job :-)
This project (unlike most of the others, but in a similar vein to Project 19) is based almost directly on the ....etc

Abstract

A transmission line trip during a power swing may cause instability of a power system. It is necessary to recognize the power swing from fault. Based on stability boundary, the power swing blocking relays must be set. To do that, first power swing should be analyzed. Second a way of probability of occurrence of fault must be found. Third, the critical condition under which the stability of a power system hasn’t been disturbed is recognized. Finally the settings of the power swing relays are calculated. In this paper analys ....etc

Circuit of an automatic switch for audio power amplifier stage is presented here. The circuit uses stereo
preamplifier output to detect the presence of audio to switch the audio power amplifier on only when
audio is present. The circuit thus helps curtail power wastage. IC1 is used as an inverting adder. The
input signals from left and right channels are combined to form a common signal for IC2, which is used
as an open loop comparator. IC3 (NE556) is a dual timer. Its second section, i.e., IC3(b), is configured
as mono ....etc

Abstract

A human's ability to perform physical tasks is limited by physical strength, not by intelligence. We define extenders as a class of robot manipulators worn by humans to augment human mechanical strength, while the wearer's intellect remains the central control system for manipulating the extender. Our research objective is to determine the ground rules for the design and control of robotic systems worn by humans through the design, construction, and control of several prototype experimental direct-drive/non-direct-drive multi-de ....etc
