Figure 4 is a current input version which is actually a CCCS,
or current controlled current source. This is truly a current
amplifier. This circuit could be useful with current output Digi-tal-to-Analog Converters (DAC’s), or in any application where
a current is available as an input.
STABILIZING THE FLOATING LOAD VCCS
Because the load is in the feedback loop on all of these
circuits, it will have a significant effect on stability. If the load
was always purely resistive, the analysis would be simple and
many circuits would not require any additional components
(such as Cf and Rd) to insure stability. In the real world however,
we usually find ourselves using these circuits to drive
such complex loads as magnetic coils and motors.
Stability analysis is most easily accomplished using “Rate of
Closure” techniques where the response of the the feedback is
plotted against the amplifier open loop gain. This technique uses
information easily obtained on any amplifier data sheet.
Rate-of-closure refers to how the response of the feedback
and amplifier Aol intersect. If the slope of the combined intersection is not over 20 dB per decade, the circuit will be stable.For an example, consider the amplifier of Figure 1A. Assume a PA07 amplifier with a 0.5 ohm current sense resistor will be used to drive a 50 μH coil with 1 ohm of series resistance. In Figure 5 we have superimposed on the Aol graph of the PA07 the response of the load and sense resistor.

可以用作元器件试验或者电机力矩控制的场合中的有效负载。力矩是电机中的电流的直接方程,所以力矩控制可以简化。饲服回路中的电流驱动减少了电机自感应造成的相位滞后,并且简化了回路的稳定性。根据负载是否需要接地,VCCS的功率工作安培将假设两个基本组合中的一个。自己翻译的,不是在线翻译的。。。

富兰克林对电学的另一重大贡献,就是通过1752年著名的风筝实验,“捕捉天电”,证明天空的闪电和地面上的电是一回事。他用金属丝把一个很大的风筝放到云层里去。金属丝的下端接了一段绳子,另在金属丝上还挂了一串钥匙。当时富兰克林一手拉住绳子,用另一手轻轻触及钥匙。于是他立即感到一阵猛烈的冲击(电击),同时还...
