<p>The device (102) has a control unit (110) for selectively deactivating inverters (104.1-104.4) and connected with the inverters and detectors (111.1-111.6). The control unit forms a sum value, which represents sum of error currents of the inverters, from detection values, and compares the sum value with a preset threshold. The control unit is deactivated during exceeding of the threshold for a preset time for falling of the threshold around a falling amount, where the amount is 0 to 50 percent of the threshold. An independent claim is also included for a method for controlling a power supply device.</p> |
