Capacitor reforming guide Introduction This guide applies to single drive frequency converters and multidrive inverter units, referred as converters later in this document. Converter DC link capacitors need to be reformed (re-aged) if the converter has been non-operational for more than one year. Without reforming capacitors may get damaged when the converter starts to operate. It is recommended to reform the capacitors once a year.
