Abstract:
The invention relates to a control transducer comprising a switch (T1; T2) with a control connection (G) and a first and second load connection (D, S), a rectifier assembly (GL1; GL2) connected to the switch (T1; T2), said assembly having output terminals (AK1, AK2), at which an output voltage (Uout) is provided for a load (RL), a controller assembly (RA1, RA2), which provides a control signal (RS; DRS) that is dependent on the output voltage (Uout) and a control circuit (AS1; AS2), which provides control pulses, according to which the switch (T1; T2) conducts or disables. According to the invention, the control circuit (AS1; AS2) generates identical control pulses consistent with the inventive method, whose frequency is dependent on the control signal (RS; DRS).

Abstract:
The method involves using at least two voltage supply modules (PS1-n) whose outputs are connected in parallel and detecting the output currents (I1-n) of the modules, providing corresponding current measurement signals, selecting a of a module as a reference signal for the other modules and setting the output current of the other modules depending on the reference current signal (SI). Independent claims are also included for the following: a voltage supply arrangement and a voltage supply module.
Abstract:
The converter stage has input terminals to which an input voltage (Uin) is applied. Control signals (S1-S4) are applied to control inputs (IN1-IN4). The output voltage (Uout) appears at an output terminal (OUT). The ADC (20) includes a main and a further input, the latter supplied with a signal dependent on the output voltage. A digital filter (30) input is connected to the ADC output. Its second input is supplied with a digital adjustment signal (Es). Its output makes a digital regulation signal (RS) available. The control signal (S1-S4) is a function of the regulation signal. An Independent claim is included for the corresponding method.

Abstract:
One embodiment of the invention relates to a switching converter having at least two converter stages, an output and an actuation circuit. The at least two converter stages each have power supply terminals for terminal to a supply voltage, a control terminal for supplying an actuation signal, an output terminal for providing an output current and a measurement terminal for providing a measurement signal which is dependent on the respective output current. The output is configured for connecting a load and providing an output voltage for the load, to which output the output terminals of the at least two converter stages are connected. The actuation circuit, to which the measurement signals and a signal which is dependent on the output voltage are supplied, provides the actuation signals. The converter stages are designed to provide a pulse-width-modulated measurement signal whose pulse duration is dependent on the respective output current.
