Abstract: The present invention relates to methods for controlling a multi-channel power supply and to corresponding devices. According to one embodiment of the invention, a method for controlling a multi-channel power supply is provided. Therein each channel comprises an intrinsic channel resistance and a resistor adjustable between a lowest resistance and a highest resistance. The method comprises the following steps: Measuring for each channel a measure indicative of a current in the respective channel; Adjusting, on the basis of the measures, the adjustable resistor in the channel having the highest intrinsic channel resistance to the lowest resistance; and Adjusting, on the basis of the measures, the adjustable resistor(s) in the remaining channel(s), such that currents in each channel are balanced. With it a concept of simultaneously performing current balancing and reduction of power dissipation is provided.

Abstract: Methods reduce transients in a redundant clock system forming part of a switch in a telecommunication network. In general, the transients, normally in the form of phase steps, are caused by reconfigurations in the clock system. Examples of reconfiguration are an inclusion or an exclusion of a redundant clock generating circuit, referred to as a plane, or an activation of a network synchronization. These transients are eliminated by successively adding an increment to a variable representative of a physical quantity in the clock generating system. In the case of an inclusion of a plane or an activation of the network synchronization, a positive increment is successively added to the gain of an amplifier. In the case of an exclusion of a plane, an increment is successively added to a phase difference representing signal.
