Concept
Matched-pair SCR’s are generally available for parallel connection, but they are very expensive. With unmatched SCR’s equal current sharing is enforced by adding a low-value resistor or inductor in series with each SCR. Forced current sharing using equal-value resistors is shown in Figure 2. The basic requirement is to make current I1 close to l2, a maximum difference of 20% is accept across SCR2, the value of R can be obtained from.
I1R + V1 = I2R + V2
I1R + V1 = I2R + V2
R = (V1 – V2)/(I2 – I1)
Calculation:
Voltage across 0.05 ohm resistor = 120 × 0.05 = 6 V
⇒ I2 = 6/0.06 = 100 A
Current through T1 will be nearly equal to 100 A
⇒ I2 = 6/0.06 = 100 A
Current through T1 will be nearly equal to 100 A
