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
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
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.
