ABSTRACT

A D.C. power supply unit was designed and constructed by the process of rectification, filtering and regulation of 60HZ mains voltage supply. The device was designed and constructed to give out an adjustable output voltage between 0-15v using a 5-way ganged switch. The device was tested and was found to give out an output current of about I Ampere, a very low output impedance of 0.190, a high rated power of about l5watts and a good regulation. Thus the device could be used as an efficient power supply in the laboratory and domestically to operate some electrical equipment.
