Yaskawa: U1000 industrial matrix drive

Green industrial matrix drive features power regeneration, reduced harmonics Engineered to save space and operate without additional components, the compact U1000 industrial matrix drive uses nine bi-directional switches arranged in a matrix to convert a three-phase AC input voltage directly into a three-phase AC output voltage. This design eliminates the need for the rectifying circuit and DC smoothing circuit used in traditional AC drive inverters. The drive returns regenerative energy directly back to the power supply (instead of using regenerative braking resistors to dissipate energy as heat), increasing energy efficiency. Additionally, matrix technology reduces total harmonic distortion levels to 5% without reactors and filters, creating a smoother current waveform that reduces stress on the system power supply and infrastructure. The reduced distortion also improves power factor to further reduce energy costs. Two models are offered: a 240-volt and 480-volt.
