Semiconductors play an important role in electrical engineering. Their conductivity may depend on the current flow direction or a control signal. Diodes are used to rectify alternating currents for smaller power outputs. If output needs to be regulated – to dim lights, for example – controllable elements such as a thyristor, IGBT or MOSFET are used.
Since ceramic capacitors and conventional electrolytic capacitors often do not meet high electrical requirements, power electronics use ultracapacitors as power storage, snap-in or screw-connected electrolytic capacitors and film capacitors.
Semiconductors are what is known as heat conductors; this means that their conductivity depends on the temperature. The higher the temperature, the better their conductivity. Semiconductors are electrically isolating at absolute zero.
