Abstract: Disclosed is a technology related to an apparatus for controlling or analyzing a power converting module, and more particularly, to a technology for improving imbalance of power quantities processed by a plurality of power converting modules. Relative power quantities processed by the modules are detected through a common circuit element installed in an input terminal or an output terminal shared by the plurality of modules, without detecting information acquired through current or voltage sensors individually installed in respective modules, and control values of the respective modules may be compensated for through the detected relative power quantities or may be output in a form where a user can easily identify them.
