    • A power pack for supplying a consumer connected to the direct voltage branch of the power pack directly or through a d.c. voltage changer has a buffer capacitor (C) that can be loaded from the supply network and which continues to supply for a set minimum time the direct voltage branch in the event of a power failure or outage. The buffer capacitor (C) can be loaded through its own loading circuit (3) up to a voltage which is substantially constant, whatever the voltage oscillations in the direct voltage branch, and which substantially corresponds to the top threshold value of the direct voltage (U1) for which the power pack is sized. The buffer capacitor can be connected to the direct voltage branch by a controlled switch (S) when voltage drops in the network or in the direct voltage branch.

    • The invention pertains to a power rectifier circuit for power supply units, especially switched mode power supply units, with a full-wave rectifier (D1...D4) on the supply voltage and, downstream thereof, a charging capacitor (CL), wherein the charging capacitor is charged through the serial connection of a boost inductor (LB) and a diode (DS) in which the interconnection point of the boost inductor with the diode is connected to frame via a controlled switch (SB), with a clock frequency considerably higher than the mains frequency; the charging capacitor (CL) as well as the load resistor (SNT) are on the full-wave rectifier (D1...D4); the serial connection of the boost inductor and diode leads to the charging capacitor through an auxiliary rectifier (D1', D2'), and the switch is controlled by a control circuit (AB) so that additional charging current is supplied to the charging capacitor in time ranges at the zero crossings of the rectified half-waves through the boost inductor.
