description A power conversion system includes: a plurality of power modules; and a control module connected to the plurality of power modules, wherein the control module includes: a current source configured to supply a switch drive current; and a main switch configured to cut off the switch drive current supplied by the current source in response to an external abnormality detected outside the power conversion system, wherein each module of the plurality of power modules includes: power conversion circuitry configured to output electric power; a power-off switch configured to cut off the electric power from the power conversion circuitry in response to a disappearance of the switch drive current supplied by the current source; and an input cutoff switch configured to cut off the switch drive current to the power-off switch in response to an internal abnormality detected inside the module, and wherein the current source and the main switch are connected to the power-off switch and the input cutoff switch for each of the plurality of power modules to provide a series connection including the plurality of power modules.
