AET-HV High Voltage frequency inverter (AC Drives, Variable frequency drive,  adjustable frequency drive)

Our high voltage(HV) frequency inverter (adjustable frequency drives) are widely applied in the following areas:

Heat power station: coal grinding machine, blower, draught fan, dust exhaust fan, circulating pump and water-feeding pump.

Iron and steel plant, metallurgical plant: water-feeding pump, dust exhaust fan, draught fan, oxygenator.

Mine: slurry pump, ventilator.

Oil: water injection pump, oil pump.

Chemical plant: compressor, blower, circulating pump.

draw off pump, supply pump, purifying pump, sewage pump in urban power supply and sewage disposal.

The grinder, pump, draught fan, dust fan, supply blower in cement plant, and ceramic plant.

others: the blower for medicine, paper making, food.

Voltage of this HV frequency inverter: kV - 10kV, or more  Single unit power of our high voltage ac drive: 315kW - 8000kW

Common feature:
Adopt A-D-AD high voltage way controlled by space voltage vector in sine wave PWM technology, transformer isolation and in-line power element.
Input end adopts move phase transformer multiple-rization technology, electric current harmonic input is minor;
Output end adopt n power-unit cascade to fold up wave technology, output voltage wave form approaches sine, electric current wave form is perfect;
Input and output harmonic waves all completely meet the standard
