In order to control the electric motors (starting, speed and torque), so-called frequency converters or inverters are used. For low power motors, low voltage applications are more common. For higher power motors, the use of medium voltage motors is much more efficient and has become standard.
To control it, frequency converters/inverters are also used, but in medium voltage. These are called VSD or VFD drives – Variable Speed/Frequency Drive).
For these, it is essential to use phase-shifting medium voltage transformers (multi-pulse), a special type of transformer capable of making these frequency converters/inverters (Power Drives) not generate harmonic content harmful to the electrical system.
Tamura Brasil has the knowledge and proven experience of over 10 years, to provide the major local and global players, the best multi-pulse phase-shift transformers of this very important equipment, both for topology contributing to the development of modern industry.
