6KV 800KW Squirrel-Cage Asynchronous And Synchronous Electric Motor Speed Controller
6KV 800KW Squirrel-Cage Asynchronous And Synchronous Electric Motor Speed Controller Medium Voltage Frequency Inverter, which is controlled by DSP, with the SVPWM and cell in series multi-level technology to guarantee the inverter to suit industrial fields. The harmonic content is much smaller than the standard of IEE519-1992. It has high power factor and good output wave quality without input filters, power factor compensation device and output filter. Motor heating caused by harmonics and Torque ripple, noise, dv/dt, and common mode voltage problems are also avoided. It fits for asynchronous and synchronous motors. The product was awarded as national key new products in 2003, high voltage hoister inverter was awarded as National Torch Project in 2005 and funded by Ministry of Science and Technology Innovation Fund for SMEs project.
