A Technique of Measuring Voltage in VVVF Frequency Convert Speed Control
A new technique of measuring voltage in VVVF frequency converting speed control is presented. Basing on single chip microcomputer MCS-8098, the technique uses synchronous sampling in hardware and quasisynchrouous sampling in programming. Some other techniques speeding up the running velocity of programming are also suggested. By DFT, an accuate result can be obtained for each harmonics.
