【Abstract】 With regard to the increasing harmonic problems caused by general purpose inverter, this paper introduces the mechanism of those harmonics and gives out the practicable engineering countermeasure. The method to calculate the harmonic current is also described in this paper, which enable users select the most suitable countermeasure and hence to meet the GB standard.更多还原
