Core functions of medium voltage applications

Master-slave control 

• Power balancing: meet the VFD output torque balancing after connecting the master-slave VFD to the motor through load connection.
• Speed synchronization: meet the VFD speed synchronization after connecting the master-slave VFD to the motor through load connection.
• Master-Slave switchover: support flexible switching between master and slave with just one click and single machine switching

Transient power loss ride-through 

When the grid transiently drops, the VFD can keep running within an effective time with the regenerative energy.

It is particularly suitable for applications requiring high continuity of equipment operation, such as belt conveyors, elevators, etc.

200% low-frequency heavy-load startup 

NPC three-level inverter technology 

• Three-level output, with low harmonic content, reducing filter size and cost.
• Reduced output voltage variation (du/dt) to minimize insulation damage to the motor.
• Lower motor common-mode voltage to reduce shaft current.

Medium-voltage product introduction 

INVT medium-voltage products for mining industry are developed based on our advanced power electronics technology and fully independently developed motor control algorithms. Combined with the application characteristics of mining equipment, we have developed three series of products: GD1000 series, GD2000 series and GD3000 series, covering voltage levels of 380V, 660V, 1140V, 3300V, and power ranges of 22kW-2500kW. These products are widely used in mining electrical equipment, such as coal mining machine, continuous mining machine, bolter miner, scraper conveyors, belt conveyors, mine hoists, local fans, and emulsion pumps for over a decade.

After more than a decade of sedimentation, INVT mining industry system solutions have been developed. These products are not only utilized in numerous domestic coal mines, both above and below ground, but also exported to foreign mines in Southeast Asia, West Asia, Africa, and Europe.

Additionally, GD3000 series products are extensively used in oil fracturing, brick wells, and pumping units, among other fields.
