Making Energy Conversion By The Switching




The idea of making energy conversion by the switching emerged in the 20s of last century, but during the subsequent three decades had little evolution. With the invention of the thyristor, the late 50s, began a major outbreak of technological developments in power electronics, which lasted for 60 years and led, in the 70s, the beginning of the deployment of power electronics in industrial scale.

The main applications of power electronics are driving machines and electrical loads of great power, direct current or alternating, through the use of thyristors and transistors with high capacity.

In addition to power electronics deals with the conditioning of electricity through electronic circuits called static converters for converting electrical power AC to DC and vice versa.

Among the industrial equipment endowed with power electronics can quote the switching power supplies, frequency converters and devices for soft start (Soft-Starter) used to control the operation of electric motors.
