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 对比传统的线性电源,开关电源具有体积小、效率高的优越性,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,因其输出精度较低、有开关纹波等因素,在高性能应用场合尚未完全取代线性电源。
The exportation resistance of a device work device with what link after loading the resistance s the certain connections for should satisfying , in order to prevent mount to load the appearance produce the obvious influence . with each other connect to say to electronics equipments , for example after signal connect the enlarger , ex - class to connect class , only behind first - degree importation resistance before larger than first - degree exportation resistance 5 - 10 times are above , can think the resistance to match good ; connect the box come saying , electronics tube the machine should choose to use with for the enlarger its output to carry the mark to call the resistance the box for , but transistor enlarger then have noing this restrict , can take officing why resistance of equal or approximate box 一件器材的输出阻抗和所连接的负载阻抗之间所应满足的某种关系,以免接上负载后对器材本身的工作状态产生明显的影响。对电子设备互连来说,例如信号源连放大器,前级连后级,只要后一级的输入阻抗大于前一级的输出阻抗5 - 10倍以上,就可认为阻抗匹配良好对于放大器连接音箱来说,电子管机应选用与其输出端标称阻抗相等或接近的音箱,而晶体管放大器则无此限制,可以接任何阻抗的音箱。
