Medium Voltage Drives Product Brochure

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
Diagram represents standard product offering: T300MVi medium voltage drive 1000 to 2000 HP, 4160 V
Input. This product was designed to have one of the smallest footprints offered by any manufacturer.
Stable Speed Control Without
a Speed-Sensing Device
