Article 455 provides the requirements for installing phase converters [Sec. 455.1]. Before installing a phase converter, read the nameplate to ensure the unit you ...

A phase converter provides three-phase power from a single-phase source. Old-style mechanical converters use a hybrid motor/generator, while electronic converters use capacitors and other devices to ...

No matter what the latest microprocessor, FPGA, or ASIC has in store, their demands always seem to be the same—the need for higher current while operating at lower voltages. A core voltage of less ...

One of the hidden complications of upgrading grain drying and handling systems is providing enough electricity to power the new larger electric motors. Electric motors that are larger than 15 hp ...

In a power-supply topology for a computer system with a 12-V input and a 1-V, 20-A output, currents are high enough that duplicate power stages can be used to reduce stress and spread the thermal ...

Server and computer system architecture has increased in tandem with power delivery (PD) requirements in recent decades. This complicates regulator design since it necessitates a compromise between ...

Variable frequency drives (VFDs) are used in many industrial applications to improve energy efficiency and provide precise control over electric motors. By adjusting the frequency, voltage and current ...
