What should be the PIV rating of diodes in the circuit
-
hello ,
I have assignment and there is the following question in it
Actually I answered some of them but I am not sure
I Drew the circuit and I tried to put here but I couldn't ,
However, these are the questions
1-what should be the PIV rating of diodes in the circuit ?
my answer :
7- the dc output voltage of the filtered rectifier is less thae it should be . what could be the problem ?
the voltage diodes dropped because of the deplition region
hello ,
I have assignment and there is the following question in it
Actually I answered some of them but I am not sure
I Drew the circuit and I tried to put here but I couldn't ,
However, these are the questions
1-what should be the PIV rating of diodes in the circuit ?
my answer :
We used bridge rectifier diode in the circuit which has PIV which should be more than 130 v in this " the maximum voltage" which should be safely applied , otherwise the diode will breakdown , also it should be at least 50 volts at room temperature because it effective by room temperature , it increase with it and decrease with it too. Another Point It is important to remember that this is a peak value of voltage not the root-mean-square (RMS) value. As a
“Rule -of-Thumb, to provide a margin of safety, the PIV rating of a diode should be at least 3 times the RMS .
“Rule -of-Thumb, to provide a margin of safety, the PIV rating of a diode should be at least 3 times the RMS .
note : 130 the input voltage
2- if one of the diode in the rectifier is opens , what should be the possible output voltage ?
3- if one of the diode in the bridge rectifier shorts what are the possible consequences ?
4- discuss the effect of change in the value of filter capacitor used ?
5- what happens to output voltage of a rectifier if the capacitor becomes very leaky ?
6- if the primary winding of the transformer in the power supply , what will you observe in the rectified output ?

Any change in the primary current will cause a change in the flux, which then induces avoltage in both the primary and secondary coils.
7- the dc output voltage of the filtered rectifier is less thae it should be . what could be the problem ?
the voltage diodes dropped because of the deplition region

please can you check my answer and help me to find the rest answer ?!!
thanks alot
