However, a currentamplifier always tries to multiply the current by a set amount.
不过，电流放大器总是设法对电流进行一定的放大。

A control circuit which is composed of a capacitor and a currentamplifier is connected in a coil circuit in series.
线圈回路中串接有由电容和电流放大器组成的控制电路。

Therefore, the proposed structure could satisfy the demands of large-capacity systems because each compensation winding has a low demand to the currentamplifier.
