| Abstract: | The driving motor of the beam-pumping unit widely used by every oil field is usually in an ineffective status, which leads to an obvious fall of work efficiency and power factor. This paper presents a new kind of system equipment in order to improve power factor, economize energy, reduce consumption and decrease production cost. The power factor and the work efficiency will always be in the high-point,with the application of chopped mode PWM AC voltage regulating technique. |
