Low-voltage frequency converter MT1000

Designed for control of asynchronous, synchronous, synchronous reactive electric motors with power from 500 kW to 2500 kW. The converter is made as a modular design, where each module is a full-fledged three-phase inverter. The inverters use the scheme of three-phase three-level inverter, as well as vector control. Advantages: Modular design - allows the entire product to remain operational in the event of failure of one or more power components; The use of three-level circuit of the power part increases the inverter efficiency (up to 98.5% instead of 96-97% in traditional frequency converters); Reduction of harmonic composition of current; Reduction of overvoltage at motor terminals allows to increase the life of electric motors, to use electric motors with lower insulation class; Reduction of bearing currents of electric motor; Reduction of heating of electric motor windings by 20%
