In a full wave junction diode rectifier, the input a.c. has r.m.s. value of `20 V`. The transformer used is a step up transformer having primary and secondary turns ratio `1: 2`. Calculate the d.c. and a.c. voltade in the recitified output.

Text Solution

Verified by Experts

Here, `V_(rms)=20V`, Peak voltage of input voltage,
`V_(0)=sqrt(2)V_(rms)=sqrt(2)xx20=28.28V`
Since the transformer is a step up transformer, having transformation ratio 1:2, the maximum value of the output voltage of the transformer applied to the diode will be
`V_(0)^(')=2xxV_(0)=2xx28.28V`
D.C. voltage `=(2V_(0)^('))/pi=(2xx(2xx28.28))/((22//7))=36V`
Output a.c. voltage `=0.48V_(0)^(')`
`=0.48xx(2xx28.28)=27.14V`
