power supply controller power supply controller - TRANSOTRONIC


The rectifier range TRANSOTRONIC is designed for the secured supply of DC power for critical loads such as control and monitoring systems as well as data processing technology in power stations and industrial plants. These plants require, a reliable power supply independent of the public net, which is most often achieved using a battery-secured power supply. Particularly in larger plants, devices with 220 V DC output and currents of several hundred amperes are used. For the conversion of AC to DC current rectifiers with thyristor bridges worked satisfactorily.

One of the disadvantages of these devices is however the harmonic distortion feedback to the mains net during the energy conversion. These harmonic distortions are produced by the ingate control of the thyristors and are able to disturb other loads also connected to the same AC mains.

Further, the net will be loaded with apparent current, due to the power factor cos φ of thyristor rectifiers being within the range of 0,7 - 0,9.
