Many older industrial facilities use single-phase, oil-filled transformers made for pole-mounting but installed at ground level to create 3-phase power distribution systems. Usually, primary and ...

Single- and three-phase alternating current (AC) motor speed can be controlled by controlling the frequency of the voltage coming to it. Motor speed has a lot to do with the capacity of refrigeration ...

A phase converter is a device that converts electric power from a single phase to multiple phases or vice versa. Most phase converters produce three-phase electric power from a single-phase source, ...

The major drawbacks of conventional diode or thyristor rectifiers are overcome by active power factor correction; this further provides additional benefits. Operating principles and features of single ...
