as Master thesis, just begins. a.) The control strategy of 3 phase PFC boost rectifier and DCDC converter are researched and designed; b.) Control strategy will be verified in the environment of MATLAB/Simulin und PLECS; c.) Hard- and Software will be implemented with DE0-Nano (FPGA) board.

1. Administration support: a.) Maintenance support of Computer Pool; b.) Documentation of process description; c.) Support for project plan, work package and appointment schedule; 2. Development support: a.) Documentation of requirement specification; b.) Documentation of test specification and test results; c.) Preparation of verification.

a.) The influences of different combinations of inverter-topology and configurations (PWM-frequency, modulation technique and dcurrent) are researched; b.) Depends on the loss characteristics of inverter (switching and conduction losses) and electric motor (copper, iron and mechanical losses) a losses Model for the calculation of the total losses of the electric drive train is proposed; c.) An optimization of the electric drive train for the driving cycle WLTP3 in terms of the efficiency is found.

HiL Test of Netzwerkmanament in Powertrain (CPC, ECM, MPC, TCM, Park, ESP, EPS, RBTM ect.).

1. Support for HV Battery Test-Team (ScienLab); 2. Support for Pre-Integration Test-Team (AVL-PUMA); 3. Support for Test-automation Team (ECU-Test).

This project was as the bachelor thesis. a.) The Rotor Flux Orientation Control for PMSM is researched, in which the mathematic model of PMSM are decoupled in d-q coordination system; b.) Simulation of the Servo Control System (current, revolution, and position loops) is built on Matlab/Simulink; c.) Hardware with the controller TMS320F2812 is designed.
