Power
electronics expression is used to distinguish the type of application that is
given to electronic devices, in this case to transform and control voltages and
currents significant levels. It differentiates this type of application and
other electronics called low power or too weak currents
In
this application the electrical and electronics are reunited, allowing for control
electronic circuits for controlling driving (on and off) power semiconductors
to handle currents and voltages in power applications is used. This to form
teams called static power converters.
Thus,
the power electronics can adapt and transform electrical energy for various
purposes such as a controlled power other equipment, transform electrical
energy continuously to AC or vice versa, and control the speed and operation of
electrical machines, etc. by using electronic devices, especially semiconductor.
This includes applications in control systems, systems for power factor
compensation and / or harmonic electric supply to industrial consumers or the
interconnection of power systems of different frequency.
The
main objective of this discipline is the handling and transformation of energy
in an efficient manner, so avoiding use resistive elements generating potential
Joule losses. The main devices are used by both coils and capacitors and
semiconductors working in cut / saturation (on / off, on and off) mode.
