IPW90R340C3 the devices used in DCDC full bridge circuit, full bridge topology circuit,
Input voltage 500 v,
A product with 4 IPW90R340C3, location is Q0500 Q0501, Q0502, Q0503
(bridge circuit on Q0500 Q0502) often is damaged, defective rate 1%。
(Q0500 Q0502) to replace two new devices, test, load can work normally.
And test for a relatively long time also no longer appear damaged, measuring device peak voltage and current are normal。
What reason? How to improve?
