9.2. GLOSSARY.
•
AC.-
Alternating current is electric current in which the mag-
nitude and direction vary cyclically. The waveform of the most
commonly used alternating current is that of a sine wave, since
this achieves a more efficient transmission of energy. In certain
applications, however, other periodic waveforms are used, such
as triangular or square.
•
Bypass.-
Manual or automatic, this is the physical connection
between the input of an electrical device and its output.
•
DC.-
Direct current is the continuous flow of electrons through
a conductor between two points with different potential. Unlike
AC, in DC, electrical loads always circulate in the same direc-
tion from the point of greatest potential to the lowest. Although
DC is commonly identified as a continuous current (for example,
that supplied by a battery), any current that always maintains the
same polarity is continuous.
•
DSP.-
Digital signal processor. A DSP is a processor or micropro-
cessor-based system that has a set of instructions, hardware and
optimised software for applications that require numerical opera-
tions at very high speed. Because of this, it is especially useful
for the processing and representation of analogue signals in real
time: in a system that works in this way -real time- samples are
usually received from an analogue/digital converter [ADC].
•
Power factor.-
The power factor, PF, of an AC circuit is defined
as the ratio between active power, P, and apparent power, S, or as
the cosine of the angle formed by the current and voltage factors,
designated in this case as cos f, where f is the value of the angle.
•
GND.-
This stands for GROUND or EARTH and, as the name indi-
cates, refers to the potential of the surface of the Earth.
•
EMI filter.-
Filter capable of significantly reducing electromag-
netic interference, EMI, which is the disturbance that occurs in a
radio receiver or in any other electrical circuit caused by electro-
magnetic radiation coming from an external source. Electromag-
netic interference is also known as radio frequency interference,
RFI. This disturbance can interrupt, degrade or limit the perfor-
mance of the circuit
•
IGBT.-
An insulated gate bipolar transistor is a semiconductor
device that is generally used as a controlled switch in power
electronics circuits. This device possesses the characteristics of
