Hello Kevin,

I think there went something wrong with the upload of the schematic. Could you please try it again?

Thank you.

Iwasaki-san,

It seems that a schematic is missing. Could you please attach it once more?

Q2: Do you mean CO and CFF? Normally these are discharged by the load. For the converter it is not a problem if they are already charged at startup, so as long as the application does not have a problem with charged CO, there is no problem of not discharging these.

Best regards,

Brigitte
