More information about power electronics

Where else the gas discharge vessels with a liquid mercury cathode still have been used to convert alternating current into direct current at the beginning of the last century, the first truly controllable power semiconductor was finally developed by General Electric in 1957. This first thyristor was the foundation of the wide range of power components nowadays. The variety of controllable and passive power semiconductors makes the drive technology from today to be able to keep everything in motion and faces day after day new challenges.

By means of these power semiconductors the current and the energy as well can be converted into different shapes, not only in terms of the type of voltage, but also the level of the voltage and its frequency. It is even impossible for occupational safety and health without power semiconductors. Only thanks to power modules, units can be shut down for protection of technology and user, for example, if it drags too much power and becomes too hot or runs too fast.

Unlike the mechanical relays and other mechanical protection mechanisms, power semiconductors have, however, no moving parts and thus are not subject to mechanical wear. Usually a rectifier can convert AC voltage to DC voltage. With help of an inverter, DC voltage can be transferred into AC voltage. DC to a higher or lower DC voltage can be achieved with a frequency converter and AC to an AC voltage with a different frequency with a frequency converter that is also known as AC power controller.

Thus, nowadays the inverters and power semiconductors are not only used in heavy machinery such as electric locomotives and classic engines, but also in high power welding machines and other heavy machines that require a soft starter. But also the ever-spreading induction cookers can only be affordable, effective and durable thanks to the use and application of power modules. The same applies to the modern hybrid vehicles. Since here a variety of machines work hand in hand, the electrical energy must also be converted into a voltage frequency, which the controlled parts of the engine can also work with.
