Control device for a DC-DC voltage converter with a voltage controller, DC converter and method for controlling a DC converter
Abstract:
The present invention relates to a control of a DC converter (10) comprising a plurality of DC converter modules (4-1, 4-2). For this purpose, a central control variable is generated for all DC converter modules for a voltage-controlled control of the DC converter. Moreover, a current-based control variable can additionally be generated for each DC converter module. The output power, in particular the output current of each DC converter module can be individually adjusted by combining the voltage-based control variable and the current-based control variable. An overload of the DC converter modules can thus be prevented.
