May 13, 2015 - Yaskawa Introduces U1000 Industrial Matrix Drive that returns regenerative energy directly back to the power supply, increasing energy efficiency and saving money. 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. This eliminates the need for a rectifying circuit and DC smoothing circuit that are used in traditional AC drive “inverters.” The result is a compact drive with full regenerative capability and reduced harmonic distortion.
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. Additionally, reduced distortion improves power factor and thus, reduces energy costs.
