Inverters: News from electrical drive technology
. electric drive technology like frequency converter, DC converters, control cabinet converters, stepper motor drivers, etc. for efficient drive technology in the Industry 4.0 environment. Inverter or frequency converters change the number of oscillations in a certain time or the frequency of alternating current or three-phase current. Rectifiers convert AC voltage into DC voltage. Inverters do the opposite.
In drive technology, frequency or DC converters are used as flexible Regulation of the speed. This allows, for example, the volume flow of a pump to be varied or a smooth start-up of a motor. Converter for electric motors are used particularly in the high performance range. The frequency converter consists of a rectifier and an inverter. The rectifier converts the alternating voltage into a direct voltage. The inverter generates the flexible output voltage from this. The voltage and frequency of the motors can be changed flexibly. The speed and the resulting speed become variable.
Brand new inverters
In the following we present the latest developments in converters and others power Electronics of NORD, KEB, Danfoss etc. In the first block you will find industry-specific applications such as for Renewable Energy, food technology or building automation. Then come the new innovations in converters & Co. for machine and plant construction.

What would a person be without the theater, without art, without actors, without performances? With art we can cross the boundaries of time and, for example, travel back to ancient Greece, to the origins of theater. But what do art and automation have in common? Quite simply: a modern theater does not work without it. This application in Łódź shows the role Mitsubishi Electric plays in this.
