3.10.13

Simple PV (photovoltaics) function

3.10.13.1 Preface

This function uses the standard XY generator to let the

power supply simulate solar panels or solar cells with

certain characteristics. The device calculates an IU table

from four typical values.

While the function is running, the user can adjust a 5

parameter called

Irradiance

to simulate different light

situations.
The most important characteristics of a solar cell are:
•

the short-circuit current (I

), the maximum current

at almost 0 V

•

the open circuit voltage (U

), which almost reaches

its maximum value even in low light situations

•

the maximum power point (MPP), at which the solar panel can provide the maximum output power

The voltage of the MPP (here: U

MPP

) lies typically 20% below U

, the current of the MPP (here: I

MPP

) lies typically

5% below I

. In case there are no definite values for the simulated solar cell available, Impp and Umpp can be

set to this rule of thumb. The device limits the I

MPP

value to I

as upper limit, the same applies to U

MPP

and U

3.10.13.2 Safety notices

Due to high capacities on the DC outputs of the power supplies of this series, not every avail

able solar inverter can be operated without problems. Check the technical specifications of the

solar inverter and probably contact the inverter’s manufacturer for an evaluation.

3.10.13.3 Usage

In the PV function, which is based upon the XY generator and an IU table, the MPP (maximum power point) is de

fined by the two adjustable parameters

Umpp

and

Impp

(also see diagram below). These parameters are usually

stated in data sheets of solar panels and have to be entered here.

The following parameters can be set for the PV function:

Parameter Range

Description

Uoc

Umpp...Nominal device voltage Open circuit voltage at no load

Isc

Impp...Nominal device current

Short-circuit current at max. load and low voltage

Umpp

0 V...Uoc

DC output voltage at the MPP

Impp

0 A...Isc

DC output current at the MPP

Schematic diagram:

Application and result:

MPP

Adjust all four parameters on screen to the desired values. Whether the

calculated IU and P curves, which result from those values, make sense or

not can be verified with tools which can visualize the curve data, such as

EPS

Power Control (only with unlocked Function Generator app) where you

could enter the same values and have the curve visualized upon button click.

While the simulation is running, the user can see from the actual values

(voltage, current, power) of the DC output, where the operating point of the

power supply resp. of the simulated solar panel is. The adjustable value

Irradiance

(0%...100% in 1% steps, see screenshot below) helps to simu

late different light situations from darkness (no power output) to the minimal

amount of light that is required to have the panel provide full power.
