How to choose inverter thyristor for endiksyon founo fonn?

1) Chwazi selon ranje frekans fonksyònman founo k ap fonn endiksyon an;

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.

2) Chwazi dapre pouvwa pwodiksyon an nan gwo fou a k ap fonn endiksyon;

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.
