TMEIC TMdrive-XL55 Medium Voltage AC Drives

6.6 kV, up to 16.000 kVA

The TMdrive-XL55 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.

TMEIC’s water cooled design and compatibility of piping materials

with de-ionized cooling system ensures that the drive has a MTBF

of more than 20 years.

TMdrive-XL55 Features and Benefits

Design Feature

• Conservative design using 4500 V IGBTs

• High energy efficiency approximately 98.6%

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

speed control range

• 36-pulse converter rectifier by using separated phase shifted

transformer

• Multiple level drive output wave form to the motor (five levels

for the 6.6 kV inverter)

• Synchronous transfer to line option with no interruption to motor

current

• Remote input isolation transformer

• 6.6 kV direct drive voltage output level

Customer Benefit

• Highly reliable operation, expected 20-year drive MTBF

• Considerable energy savings

• Capacitors not required for power factor correction

• No harmonic filter required to provide lower harmonic distortion

levels than IEEE-519-1992 guidelines

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

and energy

Suitable for standard motors due to motor friendly wave form

• Allows starting control of multiple motors with one drive

• No motor current or torque transients when the motor transitions

to the AC line

• Less power loss in drive room

• Less total space required

• Simplifies design and installation
