A circuit arrangement for voltage supply to a load in normal and active standby operation includes a first converter unit (1,2) coupled to the input terminals (K1,K2) and having a power factor controller (PFC) (1) and switching converter (2) connected in series. A second converter unit (3) is coupled to the input terminals (K1,K2) and during standby makes available an output voltage (Vstb) at the first output terminals (K7,K8). The second converter unit (3) has second terminals (K9,K10) coupled at the capacitive storage element (C1) of the PFC (1), for supplying a voltage of the second storage element (C1) during standby operation. |
