The TMdrive-MVG2 is a medium voltage, ac fed drive designed for high-efficiency and power-friendly operation in a broad range of industrial applications.

High reliability, low harmonic distortion, and high power factor operation are designed into the drive.

Specifications 
The TMdrive-MVG2 is available with four voltage classes:

• 3.3 kV Voltage Class: 3,000 - 3,300 V ac
• 6.6 kV Voltage Class: 6,000 - 6,600 V ac
• 10 kV Voltage Class: 10,000 V ac
• 11 kV Voltage Class: 11,000 V ac

• Conservative design using 1700 V IGBTs

• Highly reliable operation, expected 12-year drive MTBF

• High energy efficiency approximately 97%

• Considerable energy savings

• Diode rectifier ensures power factor greater than 95% in the speed control range

• Capacitors not required for power factor correction

• Multi-pulse converter rectifier and phase shifted transformer:

• 3.3 kV Class: 18 pulse 
  6.6 kV Class: 36 pulse 
  10 kV Class: 48 pulse 
  11 kV Class: 54 pulse

• No harmonic filter required to provide lower harmonic distortion levels than IEEE-519-1992 guidelines

• Multiple level drive output waveform to the motor (seven levels for the 6.6 kV inverter)

• No derating of motor for voltage insulation or heating is required due to motor friendly waveform

• Synchronous transfer to line option with no interruption to motor current

• Allows control of multiple motors with one drive
• No motor current or torque transients when the motor transitions to the AC line

• Input isolation transformer included in drive package

• Better motor protection
• Less total space required
• Simplifies design and installation

• Direct drive voltage output level

• No output transformer required, saving cost, mounting space, and energy
