The invention relates to a system and a method for short-circuit detection in load chains. An embodiment method for short-circuit detection includes determining a set of local reference voltages each associated with a respective load chain in a plurality of load chains, and determining a global reference voltage in accordance with the set of local reference voltages. The method also includes determining, for each load chain in the plurality of load chains, a respective per-chain reference voltage in accordance with the global reference voltage, and comparing, for each load chain in the plurality of load chains, the respective per-chain reference voltage relative to a respective measured voltage across each load chain to determine a respective short-circuit condition. 本申请涉及用于负载链中的短路检测的系统和方法。用于短路检测的示例性方法包括：确定局部参考电压的集合，每个局部参考电压都与多个负载链中的对应负载链相关联；以及根据局部参考电压的集合确定全局参考电压。该方法还包括：对于多个负载链中的每个负载链，根据全局参考电压确定对应的每链参考电压；以及对于多个负载链中的每个负载链，相对于每个负载链两端的对应测量电压来比较对应的每链参考电压，以确定对应的短路条件。
