Low Harmonic Intelligent Pump Drive

The Drives & Motion Division of Yaskawa America, Inc. (Waukegan, IL) announces the release of the U1000 iQpump drive, designed to provide extremely low harmonic distortion in a space-saving design, and the same on board intelligent pump-specific features and protection as the standard iQpump1000. This single component solution allows for seamless user transition and achieves excellent low distortion levels without the need for additional countermeasures such as passive filters or multi-pulse arrangements.

Unlike conventional drives, Yaskawa’s matrix technology employs a system of 9 bi-directional switches that are arranged in a matrix to convert a three-phase AC input voltage directly into a three phase AC output voltage. It eliminates the need for a rectifying circuit and a DC bus that are used in traditional AC inverters. Matrix technology reduces total harmonic distortion levels to less than the IEEE compliance standard of 5%, without the need for reactors and filters. The result is a smoother current waveform that reduces stress on the system power supply and infrastructure. Additionally, the U1000 iQpump improves true power factor to near unity at full load, reducing energy costs.
