The invention relates to methods for establishing control commands for electronic power converters, especially power converters with a modular design, whereby said modules are correspondingly grouped into parallel branches according to a previously found voltage system in order to provide a constant output voltage for an on-board power supply network. Said modules are also adjusted in a co-ordinated manner by means of a current control regulator which is superimposed on an output voltage regulator. The control commands for the modules are produced when one of two threshold values of a tolerance band are reached for the current regulator error iN*-iN of the total current iN flowing through the electronic power converter, whereby the width of said tolerance band can be predefined. According to the invention, a two-step strategy defines the module which is switched when an event occurs: total current reaches the upper/lower threshold value of the tolerance band. This strategy includes the following steps: 1) parallel branch p of the module is selected and 2) the position r of the row of the module of chosen branch p is selected. |
