Medium Voltage Variable Speed Drive

Is a traditional supplier of solutions in speed variation, manufacturing all the parts of a system: Input switchgear, transformer(dry-type or oil-type), frequency inverter and electric motor. The MVW01 is designed to control medium voltage induction motors. It features unique innovations, combining hardware robustness with simplicity, reliability and safety in a compact solution with few components and state-of-the-art generation technology.

MVW01 follows the same programming philosophy of the low voltage inverter line, simplifying its application. It has a multilevel topology with high-voltage IGBTs (3.3 or 6.5 kV) and optimal switching reducing the motor harmonic currents to extremely low levels. The few number of power component parts, increasing its efficiency and reliability.
The multipulse diode configuration of the input rectifier gives a high power factor in the power supply meeting IEEE 519 requirements.
In the control stage, it has a multiprocessing architecture using 32-bit processors (64-bit bus) with floating point capability and high performance, ensuring high efficiency in motor control.
