The Smart-UPS is a series of enterprise-level uninterruptible power supplies (UPS) made by American Power Conversion (APC). [1] Most of the units have a SmartSlot (with the exception of SC and SMC series) which accepts an optional interface card providing features ranging from network connectivity to temperature and humidity monitoring.

A large data-center-scale UPS being installed by electricians. An uninterruptible power supply (UPS) or uninterruptible power source is a type of continual power system that provides automated backup electric power to a load when the input power source or mains power fails.
The high power density and 6U form factor of the BladeUPS are targeted at the growing power demands of IT servers and equipment, especially blade servers. Eaton BladeUPS mounted in a 19-inch rack The BladeUPS does not fall into a defined category for UPS type as it is a hybrid of a line interactive and online architecture , which Eaton calls ...

APC Smart-UPS is a line of smaller units intended for home and office use, available as floor-standing and rackmount versions. With the exception of the Smart-UPS Online series (SURT and SRT models), Smart-UPS units are line-interactive UPS systems, running their outputs off the inverters only when the grid power is unavailable.
Schematic illustration of a supercapacitor [1] A diagram that shows a hierarchical classification of supercapacitors and capacitors of related types. A supercapacitor (SC), also called an ultracapacitor, is a high-capacity capacitor, with a capacitance value much higher than solid-state capacitors but with lower voltage limits.
Long distance HVDC lines carrying hydroelectricity from Canada's Nelson River to this converter station where it is converted to AC for use in southern Manitoba's grid. A high-voltage direct current (HVDC) electric power transmission system uses direct current (DC) for electric power transmission, in contrast with the more common alternating current (AC) transmission systems. [1]
DC to AC power conversion is the result of power switching devices, which are commonly fully controllable semiconductor power switches. The output waveforms are therefore made up of discrete values, producing fast transitions rather than smooth ones. For some applications, even a rough approximation of the sinusoidal waveform of AC power is ...
