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
