PROSOFT MVME-147A processor module low-voltage general frequency conversion output voltage is 380~650V, output power is 0.75~40OkW, working frequency is O ~-400Hz, its main circuit is AC-DC-AC circuit. Its control methods have gone through the following four generations. Sinusoidal pulse width modulation (SPWM) control mode is characterized by simple control circuit structure, low cost, and good mechanical hardness, which can meet the requirements of smooth speed regulation of general transmission, and has been widely used in various fields of industry. However, this control mode at low frequency, because the output voltage is low, the torque is significantly affected by the stator resistance voltage drop, so that the output torque is reduced. In addition, its mechanical characteristics are not as hard as the DC motor after all, dynamic torque capacity and static speed regulation performance are not satisfactory, and the system performance is not high, the control curve will change with the load, the torque response is slow, the motor torque utilization is not high, the performance is reduced at low speed due to the existence of stator resistance and inverter dead zone effect, and the stability is poor.
Therefore, PROSOFT MVME-147A processor module has developed vector control frequency conversion speed regulation. Voltage space vector (SVPWM) control mode It is based on the premise of the overall generation effect of three-phase waveform, in order to approximate the ideal circular rotating magnetic field trajectory of the motor air gap, a three-phase modulation waveform is generated at a time, and the internal tangent polygon is controlled by approximating the circle. After practical use, it has been improved by introducing frequency compensation, which can eliminate the error of speed control. The flux amplitude is estimated by feedback to eliminate the influence of stator resistance at low speed. The output voltage and current are closed to dynamic accuracy and stability. However, there are many control circuit links, and no torque adjustment is introduced, so the system performance has not been fundamentally improved.
