ABSTRACT:
A power converter includes a steady-state controller for outputting a first voltage command such that a detected power value matches a power command, a transient controller for outputting a second voltage command such that a voltage detected before the occurrence of a fault is maintained when the fault occurs, and a voltage command selector for switching the voltage command in such a way that the first voltage command is output when no power fault is detected and the sum of the first and second voltage commands is output when any power fault is detected.
