Abstrakt Abstract:

Ericsson developed the signal processing methods to be used in the digital
power to increase the performance and the functionality of the converter. In
the continuation of that the method of identifying the load of the DC/DC
converter was developed in this project.
The aim was to develop the algorithm that controls and communicate with
the DC/DC converter “BMR450”. A current sensing circuit was been made for
the voltage measurement in the DC/DC converter across the “inductor” in one
part of this project. In this research a program was made in LabView for the
communication between the DC/DC converter and LabView via PMBus.
This thesis work was based on the “National Instrument Data Acquisition
PC-6111 (NI DAQ PCI-6111)” hardware and the “3E CMM” evaluation kit
from the Ericsson. A “Point of Load (POL)” was also included with the 3E
CMM evaluation board. Both these hardware’s could be controlled from their
own software’s shipped with them. We use the LabView to control and
communicate with these hardware’s in order to do the “real time”
communication. In this report the method of communication with these
hardware’s is explained in detail. How to use the PMBus protocol to
communicate with the DC/DC converter by using the LabView is also
The problem during this work was "to be able to communicate with (two)
different hardware's in the same GUI". The LabView was used to control and
communicate with these (two) different hardware's. The idea behind using
the LabView was that the LabView works very well with the NI hardware’s.
We developed a GUI in LabView which was able to communicate with the
second hardware (3E CMM with POL) also. So it became possible to
communicate with these different hardware's we are using, in the same GUI
using LabView.
This study report proposes a solution in LabView which communicate with
hardware's PCI 6111 and POL in a same GUI. The GUI which is made in
LabView can perform calculations in the computer and then send
instructions to the dedicated converter BMR 450 via PMBus.
As the LabView provides a very good GUI, it was very interesting and
efficient to deal with these hardware's (we were using in this project) in the
same GUI created in LabView.
