Yaskawa has announced new certifications for its U1000 Matrix Drive for marine installations including; NK, BV, DNV/GL, ABS, LR and KR. This innovative technology controls the motor load by directly converting AC input voltage to AC output voltage and offers many advantages compared to conventional AC drive design, where the power conversion is AC to DC to AC. A key advantage of this Matrix technology design is that it eliminates the need for a rectifying circuit and DC smoothing circuit typically found in conventional Voltage Source Inverter (VSI) drive systems. It offers optimum efficiency and reliability for marine applications.
