Yaskawa's U1000 Industrial Matrix Drive has 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. Courtesy: YaskawaYaskawa’s U1000 Industrial Matrix Drive features low harmonic distortion and regeneration without the need for additional components. It also features 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. The U1000 Industrial Matrix drive is designed to allow the user to return regenerative energy directly back to the power supply, increasing energy efficiency and saving money.

Power quality improvement: When a conventional ac drive converts power, the input current becomes distorted, resulting in reduced power quality. Matrix technology reduces total harmonic distortion levels to 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. Other features include low input distortion and an integrated input fusing that provides 100 kA SCCR. It is IEEE-519 compliant and comes in 240 and 480 V classes.
