碩士 === 國立中山大學 === 電機工程學系 === 87 === This thesis designs and implements a DSP-based High Frequency Inverter. This system adopted scalar control rule with inner current feedback to drive the high speed induction motor of turbo molecular pump, and applied the off-line process of parameter self measurement to acquire the each electric parameter of induction motor. It could avoid the disadvantage of traditional test. By the simulation and experimental result, this thesis which designs velocity control construction with scalar control rule and accommodates the sinusoidal pulse width modulation (SPWM) switching mode could enhance the motion efficiency of motor, decrease power depletion and inhibit the motion noise of motor. It also could control motor motion smoothly at high speed.
