IGBT Drive
TMEIC Industrial Systems India Pvt Ltd offers medium voltage multilevel IGBT Drive, TMdrive-MVG2. The TMdrive-MVG2 is a general-purpose, medium-voltage, variable-frequency AC drive for industrial power ratings up to 10 MW, in the voltage range of 3/3.3 kV, 6/6.6 kV, and 10/11 kV. Featuring high-quality Japanese design and manufacture, the TMdrive-MVG2 works with existing or new induction or synchronous motors and meets users’ basic system requirements as described below: Design features: no electrolytic capacitor in main circuit is used; instead long-life film capacitors are used; conservative design using 1700-volt IGBTs (insulated gate bipolar transistor); high energy efficiency approx 97%; diode rectifier ensures power factor greater than 95% in the typical speed control range; multiple level drive output waveform to the motor (21 levels for the 6.6 kV inverter, line to line voltage, peak to peak); multi-pulse converter rectifier and phase shifted transformer: 3.3 kV class: 18 pulse; 6.6 kV class: 30 pulse; 10 kV class: 48 pulse; 11 kV class – 54 pulse; designed to keep running after utility supply-transient voltage dropouts – up to 300 msec; synchronous transfer to line option with no interruption to motor current (additional equipment required); input isolation transformer included in the drive package; and direct drive voltage output level.
