Technical data
The Agilent one-box Solar Array
Simulator (SAS) is a dc power
source that simulates the output
characteristics of a solar array. The
SAS is primarily a current source
with very low output capacitance
and is capable of simulating the I-V
curve of different arrays under dif-
ferent conditions (i.e., temperature,
age etc.). The I-V curve is program-
mable over the IEEE-488.2 bus and
is conveniently generated within
the SAS. The SAS provides three
current operating modes:
1. Simulator Mode: An internal algo-
rithm is used to approximate a
SAS I-V curve. Four input parame-
ters: Voc (open circuit voltage),
Isc (short circuit current), Imp and
Vmp (current and voltage at the
peak power point on the curve)
are needed to establish a curve
in this mode.
2. Table Mode: For a fast and
accurate I-V simulation, the SAS
provides a table mode. The I-V
curve is set by a user-defined table
of points. A table can have any
length up to 4000 points (a point
corresponds to a specific value of I
and V). As many as 30 tables may
be stored in each of the SAS built-in
volatile and non-volatile memory.
