switchboard part and control procedures for a switchboard part

摘要

The invention concerns a procedure for regulating an output voltage (U=) of a switchboard part with a power factor-corrected downward locking converter with a transmitter (6),where the downstream locking converter is fitted with a pulsating DC voltage (Uin) on the one side. The procedure is characterized by the fact that, in addition to a primary (61) and a secondary (62), the transmitter (6) has an auxiliary (63), using a value of voltage induced in the auxiliary (63) voltage (Uind) as the guide for controlling the output voltage (U=), and where the value used to regulate is determined at a given instantaneous value of the pulsating DC voltage (Uin). The invention continues to concern a switchboard part with a control element (51),established to carry out such a procedure.
