Hi, The picture is from a step down power supply of 15V, that's supply the T board where is the IGBT firing circuit. This problem can occur for a various reasons. One of them is a defective firing board, or a overcurrent due to a short circuit in the firing circuit, MTBF of the electronics componets, and others. Look at the T board and the IGBT first... Hope it helps.
