1. An uninterruptible power supply device comprising:
a plurality of power conversion modules,
each of the plurality of power conversion modules that includes a power conversion unit that converts power fed from an AC power supply or a battery external to the device and feeds the converted power to a load external to the device; and
a control module that is disposed adjacent to the plurality of power conversion modules in a left-right direction and controls power conversion of the plurality of power conversion modules,
wherein the control module includes
a thyristor unit that includes a thyristor provided in a bypass current path for outputting AC power to the load external to the device without passing through the power conversion unit of said each of the plurality of power conversion modules,
a control unit that controls the power conversion of the plurality of power conversion modules, and
a housing that accommodates the thyristor unit and the control unit,
the thyristor unit and the control unit are arranged in a front-rear direction intersecting the left-right direction in the housing of the control module,
the plurality of power conversion modules further includes
a first power conversion module and
a second power conversion module,
a first housing that accommodates the first power conversion module and a second housing that accommodates the second power conversion module are disposed along the front-rear direction,
a front surface of the first housing is configured to be exposed so as to be accessible to the first power conversion module accommodated inside the first housing from outside the first housing, and a front surface of the second housing is configured to be exposed so as to be accessible to the second power conversion module accommodated inside the second housing from outside the second housing,
the housing is disposed on a side in the left-right direction with respect to the first housing and the second housing,
both the first housing that accommodates the first power conversion module and the second housing that accommodates the second power conversion module are arranged opposite to one side portion of the housing of the control module in the left-right direction,
the control module is provided with
a first connector to electrically connect with the first power conversion module, and
a second connector to electrically connect with the second power conversion module, and
the first connector and the second connector are provided on the one side portion of the control module in the left-right direction where both the first housing that accommodates the first power conversion module and the second housing that accommodates the second power conversion module are arranged.
