Assessment of Rectifying Effects of Various Diodes in Power Supply Units Using Multisim Circuit Design Software Programme

Abstract

A power supply unit which consists of transformer (whose voltage regulated to Low Voltage Direct Current of 5v)
with the arrangement of diodes as full-wave bridge rectifiers was set up on Multisim circuit design software. The
voltage readings of eight (8) different diodes were taken before and after rectification to measure their AC and DC
response output respectively. Measurements of each diode were taken on the Multisim Circuit Design software
multimeter and oscilloscope. The result shows that the maxima and minima points on DC curve were 5.478v for
transient voltage suppressor and -32.029v for silicon controlled rectifiers respectively. The points of inflexion
ranging between 4v to 5v showed the arrangement of the best response of other rectifiers in the descending order
