Abstract: A switching regulator which substantially suppresses effects on the output voltage of noise in a direct input voltage includes a direct voltage source for producing an input voltage, and output, and a controllable electronic switch connected between the voltage source and the output, an inductance connected between the voltage source and the switch, a pulse with modulator for controlling the switch, a first saw tooth signal producing device for supplying to the pulse width modulator a saw tooth signal, and a device for producing a current proportional voltage which is proportional to current through the inductance. This current proportional voltage is supplied to the pulse width modulator. In order to substantially suppress the effects of noise on the output voltage, a second saw tooth signal is supplied to the pulse width modulator which has an amplitude proportional to a negative value of the input voltage, and supplying a further signal to the pulse width modulator which has an amplitude which is a function inversely proportional to the value of the input voltage for maintaining the arithmetic mean of the current through the inductance constant.

Abstract: In a switching controller whose error signal amplifier essentially exhibits P action, the load step performance of the switching controller is detected via an evaluation circuit. This signal is fed directly to the pulse-duration or pulse-frequency modulator for the final controlling element, substantially circumventing the error signal amplifier for the switching controller. Through this measure, output capacities of the switching controller can be reduced without stability problems.

Abstract: Method and apparatus for output current limitation of a push-pull d.c. voltage converter. The input current of the push-pull d.c. voltage converter is detected and integrated each switching cycle of push-pull switches in the current paths leading to the transformer of the converter. The integrated signal together with a reference signal are utilized to form a control signal for a pulse frequency modulator, the output of which controls the on-periods of the push-pull switches. The arithmetic mean of the output current of the push-pull d.c. voltage converter is thereby kept constant without additional power elements. Operation with a boost-type switch controller as a pre-regulator becomes possible without problems.

Abstract: A potential free actuation circuit for a pulse duration controlled electronic power switch having a control electrode and two major electrodes, the circuit including a driver stage having a control input and two major electrodes, and a pulse transformer connected for supplying control pulses to the driver stage for turning the power switch on and off. The driver stage and pulse transformer are connected and operated so that when the power switch is being turned off, its control electrode is placed at the potential of one of its major electrodes to thereby achieve greater freedom from disturbance, and so that the power switch is actuated with very low resistance by the driver stage, resulting in very short switching times which lead to low switching losses.

Abstract: In a voltage converter for switching mode, for example a push-pull voltage converter (GW), during a starting operation the switching-on pulses for the switching elements (S1, S2) are dimensioned to be of different length, specifically in such a way that the mean value of the energy-consuming current does not exceed a prescribed limiting value.By contrast with conventional methods, there is no regulation of the switching-on pulses, but the different switching-on times in a plurality of subphases are prescribed in a fixed fashion as a function of the inductance (LS) of the DC/DC voltage converter (GW).The method according to the invention ensures that the mean value of the inrush current cannot become substantially higher than a prescribed nominal value. This is advantageous, in particular, for the power supply of travelling wave amplifiers. FIG. 1

The output inductance of the regulator is split into two separate inductances each of which is fed to one leg of the push-pull circuit. The push-pull converter is expanded to a resonance converter by means of resonance capacitors. This switching regulator has a high efficiency and is particularly suitable for use in satellite power supplies.
