VFS (Variable Frequency Starter) can realize the step frequency conversion and stepless voltage regulation through the control to the thyrister. It can output 12.5 Hz, 25Hz and 50Hz frequencies, and through controlling the voltage/ frequency ratio to realize small starting current and big starting torque characteristics. At the same time, it can realize voltage slope starting, constant current starting, soft stop, brake stop and other start/stop controlling method. This technology is newly developed, and become one of the best motor starting technologies in the world.
VFS could be used in driving blower, pump, compressor and soft stop& start of HV three-phase AC asynchronous motor or synchronous motor. Also it could be used on some fixed frequency conversion condition, which could save the energy.
