Control device for DC converter, DC converter, and control method of DC converter

摘要

The present invention relates to a control for a DC converter comprising a plurality of parallel-connected DC converter modules. In the case of the above control, for the control of all DC converter modules, a common variable for voltage control is derived. Additionally, a separate current controller is provided for each DC converter module. For each DC converter module, the control parameters can be derived from each separately determined current control and a commonly determined voltage control.
