Yaskawa: Industrial matrix drive

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. 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.
