Figure 7
Rated Gross Power of Power Unit vs. Ambient Temperature at Beginning of Life
To determine the required Set-up Power see graph in Figure 7 and consider the following
example:
1)
The present site temperature is 40ºC
2)
Find 40ºC on the horizontal axis.
3)
Read vertically until intersecting the rated power curve.
4)
Read horizontally to the vertical axis to find the set-up power.
5)
Which is 113 Watts
V
set
, the voltage across the precision load, is a measure of power. The value of the precision
load (0.375 ohm) is selected to provide the optimum load condition for the TEG. The relation
-
ship between V
set
(V) and power (P) is:
P = (V
set
)
2
0.375
This relationship is shown in Figure 8. To determine the rated V
set
see the graph in Figure 8:
1)
The required power is 116 Watts
2)
Locate 116 Watts on the horizontal axis.
3)
Read vertically until intersecting the curve.
4)
Read horizontally to the vertical axis to determine rated V
set
.
5)
Which is 6.6 volts.
