Our powerflex 6000 medium voltage ac drives allow for flexibility in a variety of applications.
Marine and chemical oil and gas industries.
The commercial pressure on lv vfds and soft starter products means replacement of a product line in five years or less.
Marine and chemical oil and gas industries.
Some of these applications include fans pumps and compressors that require variable speed motor control from 2 3 11 kv.
Ac drives in this configuration are referred to as medium voltage multi level voltage source pwm drives.
Apec offers medium voltage drives from abb.
They can be applied equally well to applications requiring constant torque ct output performance as well as the traditional variable torque vt pump and fan loads.
Medium voltage drives can be either current source inverter or voltage source inverter types although vsi types are more popular due to high reliability and low harmonic distortion.
These most common in use today include three level neutral point clamp npc type 1 using high voltage power modules current source designs using reverse blocking semiconductors five level t type and modular multi level m2l as well as others.
