The choice between voltage and current excitation is generally at the discretion of the designer. In data-acquisition systems, it's not uncommon to see constant-voltage excitation used for strain and pressure sensors, while constant current excitation is used to excite resistive sensors such as RTDs or thermistors.

As voltage is increased, the I2R heating (often referred to as "self heating") of the bridge resistors cause the resistance to decrease resulting is a sensitivity change. A shift in the zero measurand output voltage (ZMO) will also decrease as excitation voltage is decreased. The excitation current is supplied to the rotor through a device called Automatic Voltage Regulator (AVR). The source of the excitation current varies from manufacturer and from different design.

This principle is very useful for voltage control: if the output voltage of the system is less than desired, the excitation current can be increased; if the output voltage is high, excitation can be decreased.

EXCITATION LOUDSPEAKER POWER SUPPLY: The coil of an electromagnetic loudspeaker must be powered by a filtered DC voltage, without the need for 

The requirements of an excitation system include reliability under all conditions of service, a simplicity of control, This high current and voltage are compared and MW signal will be generated; This rise and drop in current and voltage will be sensed by AVR through CT/PT situated at generator output bus bars, so AVR maintains rated voltage by giving more/less excitation to AC exciter.

Excitation voltage

For two-element stacked rosettes, the comparable derating factor is 3 for power, and 1.7 for bridge voltage. This discussion is based on rosettes of square grid geometry, where each grid covers essentially all of the grid(s) in the The voltage regulator has a small adjustment screw (I assume for a resistor), but this only varies the output voltage by a few volts.

Excitation voltage

When normal voltage is applied to the terminals of a transformer with the secondary circuit open, a small current will flow in the primary. This current is called as transformer excitation current and flows all the time during the operation of the transformer. All methods use an Automatic Voltage Regulator (AVR) to supply DC output to the exciter stator.

Note that with a 2.5V excitation, you'll be giving up 12dB of SNR. In your application, I'd stick with the lower excitation voltage. A boost converter will add noise that may be difficult to The additional single phase windings supply voltage to the AVR. This creates the extra excitation voltage needed when supplying non-linear loads. For linear load applications shunt, EBS, PMG and AUX excitation methods can be used. Shunt excitation is the most cost effective method.
