SPECIRL TRRnSFORITlERS FOR CDRVERTER CELME has more than 40 years of experience in the field of special transformers used for high distortion duty cycle. In this field the product customization is pushed to the extreme: during its history CELME has proved its ability to support the customer in choosing the most appropriate solution regarding the transformer used in a converter system. Mandatory, for CELME, is to meet all the requirements, even the most restrictive, and to respect them. Our transformers are designed to withstand the worst stress and keep high efficiencies with maximum...

Converter feeding Converters, also known as Variable Speed Drive (VSD), Adjustable Frequency Drive (AFD), Variable Frequency Drive (VFD), are used to control the rotation speed of electric motors in many industrial applications as, for example, pumps, rolling and paper mills, ventilators and many others. The converter operates transforming alternated current (AC) in direct current (DC), modulated on the specific signals and reconverted in alternating output current. In this way the exiting alternating current can be easily During this rectifying process, depending on type and technical...

A distribution transformer can't be suitable for this application, because harmonic distortions are ■ Higher mechanical stresses on the windings, ■ Higher temperatures on the windings, ■...
