A method for writing status data regarding the operation of a power converter (11) provided for converting an input voltage (13) to an output voltage (14) and which comprises a digital controller (16) for controlling the operation of the power converter, the digital controller being powered by the input voltage. According to the method status data related to the operation of the power converter are repeatedly received, a measure of the level of the input voltage is repeatedly received, a threshold voltage level is provided, each received measure of the input voltage is compared, upon reception, with the threshold voltage level, and at least some of the status data are written to a non-volatile storage medium (24) when a received measure of the input voltage falls short of the threshold voltage level. |
