Hi, we have a case of S120 with 2 parallel SLMs and 2 MM of 1000A each. in some cases, without any similar incidents, the IGBTs of both SLMs explode. this happened 4 times the past 2 years. the network is rather weak and some days we have spikes from thunders. i know that during regeneration if a noticeable voltage drop occurs it might rise so quickly the current through the IGBTs and burn them. Unfortunately, in SLM there is no option for IOC protection. Do you have any idea how to overcome this problem. BR Charalampos
