WESTBOROUGH, Mass., Jan. 14, 2003 — American Superconductor Corp. Tuesday announced the sale of a 1 mega-VAR (MVAR) D-VARâ„¢ voltage regulation system to wind turbine manufacturer Nordex USA Inc. This ...

Editor's note: I thought this might be a thought-provoking white paper for Power Engineers in our audience. It's quite in-depth but will surely lead to some excellent insights into controlability and ...

Simply connecting a power supply to a load is not always so simple. Voltage drop due to wires, cables, connectors and circuit board traces can cause considerable regulation errors at the load. It is ...

Integrated circuits require a variety of voltages and a wide range of currents, typically supplied by voltage regulators. But increasing power density is resulting in higher power delivery losses.

When a tightly regulated supply voltage is needed, the DC voltage accuracy specification in a switching regulator’s data sheet can be utilised. This value is usually ±1% or ±0.5%. If the voltage ...

Power quality personnel at utilities and industrial facilities worldwide are familiar with the potential negative consequences of voltage sags. However, more than 80% of all power disturbances last ...

A well-known solution for electrical noise in industrial plants is the constant-voltage transformer, or CVT. These devices can filter distortion and notches from input voltages (see Fig. 1). CVTs have ...

For as versatile and inexpensive as switch-mode power supplies are at all kinds of different tasks, they’re not always the ideal choice for every DC-DC circuit. Although they can do almost any job in ...
