POWER SUPPLY SYSTEM

The present disclosure relates to a power supply system (100), which comprises a high voltage battery pack (110) comprising a plurality of battery modules (102), which are electrically connected in series to form the high voltage battery pack (110), which is configured to output a predetermined high voltage as a sum of module voltages provided by the plurality of battery modules (102). The power supply system (100) further comprises a low voltage output terminal (116a, 116b), which is configured to output a predetermined low voltage to at least one electric load, and a voltage converter network (106), which is configured to electrically insulate the low voltage output terminal (116a, 116b) from the high voltage battery pack (110) and to convert at least a part of the module voltages into the predetermined low voltage. The voltage converter network (106) comprises at least one voltage converter (108), which is electrically connected to at least one of the plurality of battery modules (102) and is configured to convert the module voltage provided by the at least one of the plurality of battery modules (102) into the predetermined low voltage and to output the predetermined low voltage as an output voltage to the low voltage output terminal (116a, 116b), and a controller, which is configured to control an operation of the at least one voltage converter.
