Power supply system and detection system for determining an unbalanced current condition and an overcurrent condition in a DC-DC voltage converter
A power supply system having a detection system for determining an unbalanced current condition and an over-current condition in a DC-DC voltage converter is provided. The detection system has a detection circuit that outputs a first diagnostic voltage indicating an unbalanced current condition between first and second switching banks in the DC-DC voltage converter based on a first voltage and an average voltage, or an over-current condition in the first switching bank based on the first voltage. The detection circuit outputs a second diagnostic voltage indicating the unbalanced current condition between the first and second switching banks in the DC-DC voltage converter based on a second voltage and the average voltage, or an over-current condition in the second switching bank based on the second voltage.
