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 different conditions (i.e., temperature,
age etc.). The I-V curve is programmable 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 algorithm is used to approximate a
SAS I-V curve. Four input parameters: 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.

Non-volatile memory can store a
maximum of 3500 points. The tables
(I-V curves) are easily stored and
recalled with an IEEE-488.2 command. The table(s) stored in this
memory will be retained when the
power is turned off. Volatile memory greatly increases the flexibility
by saving up to 30,000 points.
Multiple tables are easily accessed
with IEEE-488.2 command. These
tables will be erased after power
is removed.
In Table Mode, current and voltage
offsets can be applied to the selected table to simulate a change in the
operating conditions of the solar
array.
3. Fixed Mode: This is the default
mode when the unit is powered on.
The unit has the rectangular I-V
characteristics of a standard power
supply, when an output capacitor is
added in this mode.
