Uncontrolled Rectifiers When A.C. power supply is available, then, D.C. power can be supplied to D.C.,motors by the following methods (as mentioned above) :
A rectifier is a device which converts alternating voltage or current into unidirectional voltage or current. In a rectifier the conduction takes place in one direction only. P-N junction diode, which conducts when forward biased and practically does not conduct when reverse biased,can be used for rectification. Such rectifiers may be either half wave or full wave.Since undirectional voltage available from such a rectifier is of fixed value depending upon the magnitude of A.C. input voltage so such a rectifier is called the uncontrolled rectifier. | |
