How to choose inverter thyristor for induction inonyungudutsa choto?

1) Sarudza zvinoenderana neanoshanda frequency renji ye induction inonyungudika choto;

The frequency is 100HZ—500HZ and the selected turn-off time is 20µs-45µs KK type thyristor.

The frequency is 500HZ—1000HZ and the selected turn-off time is 18μs-25μs KK type thyristor.

The frequency is 1000HZ—2500HZ and the selected turn-off time is 12μs-18μs KK type thyristor.

KKG-type thyristor with a frequency of 2500HZ—4000HZ and a selected turn-off time of 10µs-14µs.

The frequency is 4000HZ—8000HZ, and the selected turn-off time is 6μs—9μs KA type SCR.

According to the theoretical calculation of the parallel bridge inverter circuit, the current flowing through each thyristor is 0.455 times the total current. Considering that enough space is left, a thyristor with the same size as the rated current is usually selected.
