例如针对数字音源和模拟音源,甚至是需要更高电流要求的功放环节,而来自美国的着名发烧音响线材品牌Audioquest(线圣)在电源线方面则进行了更多的细分,以Storm系列旗下的FireBird电源线为例,分别针对音源类和功放类推出了Source/Constant-Current和High (Variable)Current两款电源线,而本次我着重向大家介绍后者。

Single current range, no relay shifting. Short-term stability is typically better than 0.003% * FS. The maximum load voltage of the constant current output is 10 V. The unipolar source can be connected to an external commutator (accessory) to realize current commutation. A bipolar s...
The above strategy only realizes the output of a single constant current. In practical applications, a more challenging fact is that MRD should vary the damping force quickly according to environmental requirements. In other words, the SSBC current source must also change the output current rapidly...
20.2.1 Current-driven Devices A current-driven device is a device that requires a constant current drive for a period of time in order to initiate and/or remain in conduction. Two popular types of current controlled devices are the bipolar power transistor and the thyristor (SCRs). The SCR ...
and applied to the IC's feedback terminal (FB). The IC's internal control loop then maintains voltage on the FB pin constant at approximately 1.22V. Thus, a higher control voltage results in lower current, because the sum of the control and current-sense voltages (scaled by R1 and R5)...
