High Voltage Drives

 

Brief Introduction

 

MaxWell-H series high voltage drives can be used in a wide range of applications and can meet the requirements for variable frequency speed control and energy saving of high voltage motors in a variety of complex situations.

 

Input current harmonics

Multi-pulse rectification using transformer phase shift technology, 30 pulses for 6kv systems and 48 pulses for 10kv systems. Meets IEEE519-2014 standard. Input filterless.

 

Input power factor

The input transformer phase shift technology combined with cascade modules provide the reactive power required by the motor with an input power factor of up to 0.96. After the motor has passed through the high voltage inverter, no reactive power compensation equipment is required.

 

Output voltage waveform

Module-cascaded technology, H-bridge inverter, module output superimposed to form multilevel, output perfect sine wave to ensure the motor work in better condition. It is adaptable to new and old motor.
