HVAC matrix drive provides low harmonic distortion
Yaskawa's Z1000U HVAC Matrix Drive is designed to provide low harmonic distortion without the need for countermeasures like passive filters or multi-pulse arrangements.
Yaskawa's Z1000U HVAC Matrix Drive is designed to provide low harmonic distortion in a space-saving design without the need for countermeasures like passive filters or multi-pulse arrangements. The 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. It eliminates the need for a rectifying circuit and a dc bus that are used in traditional ac drive inverters. Additionally, reduced distortion is designed to improve displacement power factor to 0.98 through the entire load and speed range, reducing energy costs. Other features include an integrated input fusing to provide 100kA SCCR and an integrated C2 EMC filter. It also has eco-mode and embedded BACnet communications. It has a multi-language LCD operator with hand/off/auto and copy function and an internal real-time clock for event stamping. Available NEMA 1 models include ratings of 1 to 100 hp (208 V) and 7.5 to 350 hp (480 V). Z1000U is offered both as a stand-alone drive as well as in packaged bypass and configured solutions.
