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.

Multi-Level PWM Output Closely 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
