9.2. GLOSSARY.
•
AC.
Alternating current is electric current in which the
magnitude 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 direction 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
microprocessor-based system that has a set of instructions,
hardware and optimised software for applications that
require numerical operations 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
indicates, refers to the potential of the surface of the Earth.
•
EMI filter.
Filter capable of significantly reducing
electromagnetic interference (EMI), which is the disturbance
that occurs in a radio receiver or in any other electrical
circuit caused by electromagnetic radiation coming from an
external source. Electromagnetic interference is also known
as radio frequency interference (RFI). This disturbance can
interrupt, degrade or limit the performance 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 the gate signals of field effect transistors
with the capacity for high current and low saturation voltage
of the bipolar transistor, combining an isolated FET gate for
input and control and a bipolar transistor as a single switch
in a single device. The IGBT’s excitation circuit is similar to
that of the MOSFET, while the conducting characteristics
