Toshiba T300MVi User Manual

MEDIUM VOLTAGE DRIVES

T300MVi

 Small Footprint

Reduced Component Count

IEEE-519 1992 Compliant with 24-Pulse

Harmonic Cancellation

Additive PWM Output Voltage with No Neutral Shift

May be Used with Standard Motors

Ten-Year Mean Time Between Failures

Built in Harmonic Reduction, Without Filtering or Concern for
Long Lead Lengths

Toshiba’s T300MVi contains specially designed transformer and rectifier schemes that provide phase-shift
cancellation capabilities, eliminating issues concerning harmonic injections into bus-fed equipment. Instead,
the T300MVi medium voltage drive simply looks like a linear load on the incoming AC line. The drive also exceeds
IEEE-519 requirements without the addition of any harmonic filters.

Other Benefits:

• Topology Provides Isolation from Ground Faults and Line Surges

• Design Obtains Higher Displacement Power Factor (0.96) than Running Motor Across the Line

• Motor Torque Ripple Negligible Due to Extremely Small Harmonic Current Contents, Reducing Need for Damping

Devices, e.g., Couplings, Flywheels

• Reduces Possibility of Drive-Induced Torsional Vibration in Driven Equipment

IGBT Technology: Tried and True

Over the years, IGBT technology has proven to be the most
reliable and best performing means of speed control in low
voltage drives. Toshiba has mastered this technology, and
continues to excel at it. The T300MVi is designed using
both diodes and IGBTs in the main power circuit. We offer a
control circuit topology providing higher performance than our
competition while using fewer parts. What does this mean to
our customers? Plain and simple -- fewer parts equals lower
maintenance. This philosophy is integrated into our modular
vertical design to provide power module interchangeability and
smaller footprints than offered by competitors.

Other Advantages of IGBT Technology:

• Inherent Short Circuit and Ground-Fault Immunity at Output

• Lower Gating Power Requirements

• Small Snubber Circuitry Required

All T300MVi drives
use a three-power
module design for
reduced MTTR.
The special racking
mechanism extends
from the drive
to allow module
inspection.
In addition, the
drive does not
contain fans,
contactors,
or large electrolytic
capacitors.

Toshiba guarantees the

T300MVi product line will meet or

exceed IEEE-519 standards at input

to the drive. As a result, the drive

appears to be a linear load to the

power system.

The T300MVi design eliminates the

need for costly and time-consuming

harmonic analysis.

Simulates True Sinewave

The T300MVi drive employs several layers of switching
devices to provide a smooth output wave to the motor.
The multi-step output closely simulates sine wave shape ,
virtually eliminating motor failures due to insulation stress and
long lead-length issues.

The T300MVi drive’s topology allows retrofitting to existing
medium voltage motors without upgrading motor insulation.
It also:

• Eliminates Need for an Output Transformer,

Reducing Cost and Size

• Allows Use of Standard Bearings Without Grounding

or Isolation Means

• Operates Motor at Design Rating (Maximum)

• Enables Easy Retrofit
