摘要： A circuit arrangement for soft-switching bridge-type converters has the connecting conductor joining the first terminal of a first diode to the first terminal of a second diode connected to the first winding terminal of the first discrete inductance. The second terminal of the first diode is connected into the circuit so that the first diode lies in a first current circuit with the first electronic power switch and the first discrete inductance, and the second terminal of the second diode is connected in the circuit so that the second diode lies with the second electronic power switch and the first discrete inductance in the second current circuit.

摘要： A method for stabilising a DC voltage by means of a switched, saturated inductor. The method relates to the stabilisation of a DC voltage which has been produced from an unstable AC voltage, which is characterised by an on-phase and an off-phase, by rectification, averaging and the assistance of a saturated inductor. The inductor is connected in series with the AC voltage source and controls the power flow from said source to the load by a specific, unsaturated magnetisation state being impressed on it at the start of the on-phase in order that the load current to the load, which occurs with saturation of the inductor, is delayed in a metered manner. Known methods adjust the unsaturated magnetisation state with relatively high losses in the actuating element. According to the invention, the magnetisation state of the inductor at the start of the on-phase is brought about in an objective manner and with low losses in that said inductor is demagnetised virtually down to the desired value during the off-phase via the same circuit which carries the load current, and is short-circuited from this point in time to the end of the off-phase, in order to maintain the magnetic field. The method is used in the case of switched power supply units (switched-mode power supplies) for stabilisation of the unregulated outputs.

摘要： Two synchronous phase-locked alternating sources (4,5) with the same attributes are connected to bridge rectifiers (2,3) wired in parallel. If a switch (1) opens, the alternating sources connect in parallel; if it closes, diodes (9,10) rectify voltages (U1,U2) in series in an AC half cycle. Voltage on a load (8) goes from single to double rectified voltage and maximum current through the load drops from double to single maximum current value for an alternating source.

摘要： Utilising the relatively strong paramagnetic properties of oxygen, with the aid of the special magnetic filter construction according to the invention having filter elements comprising magnetisable material, the oxygen portion of an oxygen-containing gas mixture flowing through these elements is greatly enriched. Different embodiments are proposed for the construction of the filter elements, that is to say a slotted sheet metal construction of permanently magnetisable material and a package construction of non-permanently magnetisable yoke sheet metal packages and permanently magnetisable longitudinal bridges. Diverse embodiments of these fundamental solutions according to the invention achieve further technical advantages which are aimed both at an increase of the filter activity and at specific applications. The increase of the activity in the enrichment of oxygen in the filtered gas mixture is achieved, inter alia, by the proposed measures for improved intake by suction of the oxygen from the external region of the magnetic field. The further proposals aimed at particular applications deal with, inter alia, the use of the magnetic filter in internal combustion engines in order to reduce the pollutant content of the exhaust gases of the same.

摘要： The circuit enables an a.c. voltage or current source to be matched to a load by rectification and current or voltage changeover. A winding (4a) has a center tapping (5a) and first and second free winding connections connected to the a.c. voltage connections of a bridge rectifier (6a), whose positive d.c. voltage connection is connected to the positive output (17a) of the mains stage and whose negative output is connected to a switch (16a). A diode (15a) has its cathode connected to the tapping and its anode connected to the other switch connection and to the negative output (18a) of the mains stage. Independent claims are also included for an arrangement for continuously varying output parameters, for a voltage switching method, for a method of continuously varying the component's output voltage, forma method of switching the voltage and current at the output of a two-stage cascade and for an arrangement with a measurement circuit.
