1. 1. Signal Processing of DC/DC converter inductor current measurement

   Kandidat-uppsats, Blekinge Tekniska Högskola/Sektionen för ingenjörsvetenskap

   Författare :Yinjia Li; Zakir Hussain Ranizai; [2013]
   Nyckelord :Signal processing; Buck converter; filter design; slope; average value; DC DC converter;

   Sammanfattning : This thesis is one part of ongoing research project of Ericsson AB together with Blekinge institute of technology on the aspect of Ericsson Power modules. The aim of this project is to apply signal processing method on the measured current signal of inductor component of Ericsson BMR 450 Buck converter by using software Matlab, the method should be able to remove the noisy part which exists on the measured signal, so the signal can be undulated within normal range.

3. 2. Simulation of the BMR450 DC/DC converter

   Master-uppsats, Blekinge Tekniska Högskola/Sektionen för ingenjörsvetenskap

   Författare :Sriharsha Santhapur; Shivachaitanya Mamdur; [2011]
   Nyckelord :DC DC converter; BMR 450; Buck converter; MATLAB Simulink; PID Controller; state space analysis; Network Analysis; SimPowersystems;

   Sammanfattning : This thesis is a part of collaborated project between Ericsson AB and Blekinge Institute of Technology to develop signal processing methods to be used in digital power in order to increase the functionality, performance and reliability of dc-dc converters. The task of this project work is to model a buck converter and a measurement system to sense the inductor current and output voltages of the buck converter system of Ericsson’s BMR450. LÄS MER

4. 3. Modelling and control of a Buck converter

   Kandidat-uppsats, Blekinge Tekniska Högskola/Sektionen för ingenjörsvetenskap

   Författare :Shun Yang; [2011]
   Nyckelord :polynomial controller; second order; buck converter;

   Sammanfattning : DC/DC buck converters are cascaded in order to generate proper load voltages. Rectified line voltage is normally converted to 48V, which then, by a bus voltage regulating converter also called the line conditioner converter, is converted to the bus voltage, e.g. 12V. LÄS MER

5. 4. Communication for adaptive control

   Master-uppsats, Blekinge Tekniska Högskola/Sektionen för ingenjörsvetenskap

   Författare :Abdul Mubeen Malik; [2010]
   Nyckelord :Adaptive control; 3E-CMM; Kraftomvandlare;

   Sammanfattning : 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. LÄS MER
