Having overcome the disadvantages of ponderous , inefficient linear power source , switch power supplies are widely applied in power motion , industrial , communication , pc , office and family electronics equipment etc . but the ripple and low precision make it impossible to replace linear power source completely 开关电源克服了传统线性电源体积笨重、效率低的缺点,从而在电力传动、微型计算机、家用电器、通讯电源等领域中得到广泛应用。然而,因输出精度较低、有开关纹波等因素,在仪用电源方面目前还不能完全代替线性电源。
It is necessary to study the mechanism of harmonics generation , make sure the content and distribute of harmonics current in order to alleviate their harm to traction power system ' s component , equipments of protect and measure as well as other customer ' s electronics equipments 为了从根本上抑制电力牵引负荷谐波带来的影响,削弱谐波对牵引供电系统主元件、保护测控装置和其他用户电子设备的影响,有必要研究电气化铁道牵引谐波产生的机理,确定馈线电流谐波的含量与分布状况。
