Step 1

The power dissipated in the thyristor can be calculated using the formula: Pthy = I^2 * RT where I is the current flowing through the thyristor and RT is the resistance of the thyristor. Given that the current flowing through the thyristor is 4A (IA = 4A), and Show more…

Current flows through the circuit controlled by a thyristor working with a cooler, as shown in Figure 1. Thyristor core values are UT0 = 1 V, RT = 20 mÎ©. RthJS = 0.20 Â°C/W, RthSA = 0.30 Â°C/W, and ambient temperature TA = 25 Â°C. Operating Temperature: Between -55 Â°C and 150 Â°C. a) Calculate the total power loss. b) Find the maximum DC current that can be poured when the joint temperature is 135 Â°C (IOrt = IEf = IDC = Id). Then, find the maximum current that can flow when the joint temperature is 135 Â°C. IA = 4A Im = 120 IOrt = 1A t = 10 t2 = T = 30
