Abstract
The Root Mean Square (RMS) measurements of
alternating signal are frequently done by means of thermal
transfer instruments. The principle of these thermal
transfer instruments is to transfer the heating energy of
resistive load to a temperature-sensing element. The DC
output of the sensor gauges the amount of electrical power
(AC or DC) applied to the input. The paper examines
performance of an RMS-DC thermal converter of a solid
state technology type at various frequencies such as
LT1088CD integrated circuit. The theoretical and
simulation analysis is carried out to outline the factors
influencing the transfer characteristics of the converter
device in the DC and AC input regimes.
