| Abstract: | This paper describes a microcomputer-based PWM inverter asychronous motor speed control system. In the power circuit of this system advanced power electronic devices, power-MOS-FETS, is used to complete DC-AC convertion. In the control circuit a single-chip microcomputer of MCS-51 famalies together with a purpose-designed LSI circuit, THP4752, is applied to adjust the motor's speed by controlling the motor's slip frequency. |
