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
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
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.
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.
