The constant voltage power source using the morgan circuit
Xing Jin · Experimental Technology and Management · 2007
This paper offers,firstly,some improvements on the Morgan circuit in order to make it peculiarly suitable for different kinds of practical applications;namely,the smoothing filter is made as small as possible to make the response of the circuit rapid,while the efficiency is kept high.Secondly,data,obtained through the analysis of the operation in the case of the small filter,are presented.Thirdly,the paper shows,as the result of such analysis,that if a saturable current transformer(SCT) is designed properly,the circuit will behave as a self-regulating constant voltage power source.Lastly,it proposes a practical application which has a suitable protecting circuit composed of some simple circuit elements providing against the failure of commutation which causes a severe overvoltage and overcurrent to the load.
