INTRODUCTION AND SCOPE
1 INTRODUCTION AND SCOPE PHD PROJECT
The master thesis is part of a PHD project titled “Integrated charger for plug‐in Hybrid Electric Vehicles”. The PHD project is funded by the Swedish Hybrid Vehicle Centre (SHC1) and is doing by the PHD student Saeid Haghbin under supervision of Associate Professor Ola Carlson. Moreover, Assistant Professor Sonja Lundmark is the project co supervisor.
The scope of the PhD project is :
Investigating and evaluating existing plug in HEV’s in general and especially the charging systems. This collection of available information also includes listing all as well as the most interesting parameters of the charger, i.e. speed of charging, power rating, cost, volume and weight, number of phases, voltage levels, ease of charging and availability of charging places, limitations on power electronic components, power factor, harmonic distortion, monitoring equipment, standards, and persons safety. The study should involve battery knowledge, so that the charger could be fully adapted to the battery, giving a long battery life length.
Suggest and evaluate possible integrated chargers, meaning integration of the charger and the available drive system used for propulsion of the vehicle.
Prototype building in cooperation with the whole group (including industry). One prototype coordinator from industry administrates the task. The task also incorporates preparations for lab testing.
MASTER THESIS SCOPE
The thesis is part on the sub project “On Board Integrated Charging”. The main goal is to design, simulate and implement a 3‐phase boost battery charger with power factor correction.

The Figure 1.1 represent our system. The first idea was to use an AC motor on the AC side. Some data are given is Table 1.1.
1 SHC is composed with three different partners : three universities with Lund Institute of Technology (LTH), Royal Institute of Technology (KTH) and Chalmers University of Technology (CTH), The Swedish Energy Agency (Energimyndigheten) and automotive industry with AB Volvo, Volvo Car Corporation, Saab Automobile AB, GM Powertrain Sweden AB, Scania CV AB, BAE Systems Hägglunds AB.
