in this image if i removed the diode and Placed a thyristor
how can i find the value of R , Vr , Ir and the better type of thyristor for this circuits if i know the input is AC 220 volt and 50 Hz and power on the R is 10 K watt

 

Your Question is rather confusing !!

 

why ??
i can explain it for you

 

Ask clearly. Provide all the info you have.
Partial questions might be ignored.

 

ok
in the circuits diode be replaced by thyristor ok
all information is:
input voltage 220 and 60 Hz
power on the load 10 k watt

i need to calculation the value of Resistance , the current into the Resistance and voltage on Resistance
how can i found it

 

The ONLY resistance I see is the Load.

Unless you give a schematic, we cannot give any meaningful answers.

Please tell us what you are intending to do. Why do you want to replace the Diode by a Thyristor? In the present setup, the Load has a Pulsating DC. A thyristor in place of the Diode will give a clipped AC.

 

yes the resistance is the load i mean it
i want to do a homework about single phase full wave controlled rectifier center tap with 10 k watt
i replace the diode because i need controlled rectifier

 

what voltage is the secondary winding , what is the current?

 

the voltage in the primary is 220 volt so in the secondary will be 110 on the up half and 110 on the down half
the current i don't know its value
if i give you the wave can it help you

 

That secondary is 110VAC-0V-110VAC.
The Power of the R is 10KW.

Assuming the former is delivering and R dissipating 10KW.
From the diagram you provided, ⇒
Vdc = 0.45 X 220VAC ⇒ 99VDC.
So, Now you know DC voltage.
Use ohms law and Power = VI equations to find R and I.

 

ok thank you
but Vdc = 0.45 * 220
can you tell me the 0.45 from where

and the Vdc its the same v

 

Vdc is the Voltage seen by the R.
0.45 x 220VAC ⇒⇒ 0.45 is really the formula used for center tap Bridge rectifier without a smoothing capacitor and 220VAC is the AC voltage available at the Tx secondary across the entire coil.

 

thank you very much
