    Vacon Frequency Converter - repair

    Hello everyone!

    I have a faulty 440V AC frequency converter used onboard ship for supplying of 440V 3phase electric motor which is used to open and close covers of cargo holds.

    Its made of two parts, power module and some kind of controller. Few days ago it suddenly stopped working by means of no power on its outlet while controller kept working, showing 0 amps on output.

    I've dismantled it and found a suspicious burning spots around one component which I think is some kind of voltage regulator but I have no idea how to specify what type it is. I hope someone more experianced can help me here.

    I hope attached photos will be of some help. Thank you!
