Abstract
Provided is an uninterruptible power supply apparatus that can properly adjust the capacity of cooling a heat radiation source. A housing for housing an uninterruptible power module is provided with a cooling fan for cooling the internal space of the housing. The housing is further formed with an opening. The opening formed in one housing and the opening formed in an adjacent housing for housing another uninterruptible power module are configured to face each other. Furthermore, each uninterruptible power module includes a fan control circuit for controlling the cooling fan. The fan control circuit controls the actuation and suspension of the cooling fan on the basis of a total load of the plurality of uninterruptible power modules.
Claims5
An uninterruptible power supply apparatus provided with a plurality of uninterruptible power modules connected in parallel between an AC power source and a load, and a bypass circuit,
- said uninterruptible power modules each including:
- a converter for converting AC power supplied from said AC power source into DC power;
- a power storage device for storing the DC power converted by said converter;
- an inverter for converting DC power supplied from said converter or said power storage device into AC power;
- a housing for housing said converter and said inverter;
- a cooling fan for cooling the interior of said housing;
- said housing being formed with an opening, and said opening and an opening formed in an adjacent housing for housing another uninterruptible power module being configured to face each other, and
- a fan control circuit for controlling said cooling fan, said fan control circuit being configured to control the actuation and suspension of said cooling fan on the basis of a total load of said plurality of uninterruptible power modules.
