<p>The invention relates to a power converter stage (2) for providing power supply to a power converter controller (3), a power converter controller (3) for such power converter stage (2), a power converter (1) including such power converter stage (2) and such power converter controller (3), a method for providing power to a controller (3) of a power converter (1) and a software product for controlling a power converter (1). In order to provide for auxiliary power supply for control circuitry of a power converter (1) during all operation modes of the power converter (1) while avoiding additional costs involved with providing a dedicated control power supply fed from bus voltage, it is proposed that power stored in power storing means (4, 5) included in a power converter stage (2) or more generally in a power converter (1) are used for supply to the controller (3) even if the power converter is in stand-by mode, as a transfer of power between such power storing means (4,5) through a primary inductance (6) may be used for providing also for a power transfer to a secondary inductance (7), which then supplies the controller (3).</p> |
