| Abstract: | The cause of harmonic current in motor speed regulation and its harm to the power supply system are discussed. But the harmonic current has been restricted within necessary limits according to new national and international EMC standards. The traditional regulation method can not pass these standards. By analysis of relative international standards, the solutions of this problem were presented. The output simulation waves verify the good performance of HFM. |
