METHOD FOR CONTROLLING A POWER SOURCE, AND POWER SOURCE AND PROCESS CONTROLLER THEREFOR

摘要

The invention relates to a method for controlling a power source. The power source comprises a first converter (1) for converting an input voltage (UE) to an intermediate circuit voltage (UZK, UZKI), an intermediate circuit capacitor (2) and a second converter (3) for converting the intermediate circuit voltage (UZK, UZKI) to an output voltage (UA). A process is being controlled at the output of the second converter (3). A digital process controller predetermines at least one parameter and/or the value thereof to control the intermediate circuit voltage (UZK, UZKI) for the first converter (1) depending on an event at the output.
