Abstract: A power converter and a method are disclosed. The power converter includes a plurality of converting modules and a plurality of switching circuits. Each of the converting modules includes a bypass element configured to be shorted when a fault occurs. The switching circuits are electrically coupled in series to each other and electrically coupled in parallel to the converting modules respectively. Any one of the switching circuits is configured to be shorted when the bypass element of the corresponding converting module is shorted.
