The
Advance Unipolar amplifiers incorporate a current loop
gain selection feature (CGC).
This feature is required for the optimization of the current
loop gain. When the load impedance is too low or the DC bus
is too high, current loop instability may occur. This is when
the user has to switch from the default CGC=high to CGC=low.
The following form allows you to enter amplifier's type and
operating voltage. Once you enter this information, click the
Calculate button. Two inductance values will be calculated for
you. The first one is the minimum inductance for CGC=high. The
second value is for CGC=low.
You may want to refer to the application note AUP_step for a
detailed explanation about amplifier response in different system
conditions. |
