Abstract

Introduces full-digital variable frequency speed regulation (VFSR) system based on TMS320F2812 control, adopting SPWM technology convert 380V, 50Hz three-phase alternating current into 220V output variable-frequency alternating current. Under normal working condition, when load is changing, this frequency converter will automatically adjust the output voltage and frequency to maintain its function, system output frequency is 100Hz~400Hz. Power factor is 0.85,stable voltage varies less than plusmn2% and stable frequency varies less than plusmn1%₀ THD of output voltage is less than 5%, odd harmonic THD is less than 3%₀ Efficiency exceeds 85 %_0.
