| Abstract: | By using the operation principle and mathematical model of PWM rectifier, it is proposed that the current control principle of PI adjustment in high-capacity frequency converter and flow chart of software implementation are used. The converter is used in the AC frequency conversion motor used in pumping unit, by which stable starting, braking and speed adjustment can be obtained in the pumping unit, also energy can be feedback for energy saving. |
