One member of that research team is the University of Applied Sciences Augsburg which is performing the subproject “High efficient PFC‐topologies with a Zero‐Power control system”. This project is divided on two operation areas. The research subproject which is described below is concerned with “Digital controlled bridgeless power‐factor‐correction converter with integrated filter components”. The base of this project is a bridgeless PFC‐topology with an integrated EMI‐filter recently designed and released by Dr. Wenqi Zhou. Figure 1 shows the circuit of that power‐factor‐
correction converter including the EMI‐filter. For the actual state the input current through the PFC‐inductivities has been measured via current‐transformers. The technical target of the research subproject is to dispense the complete current measurement. Concerning this matter the complete digital control should be realised only with a measurement of the input and output voltage together with a DSP microcontroller. The further task of this project is to research and develop integrated electrical filter components. Referring to this the PFC‐inductivities and the filter inductivity of the EMI‐filter should be combined to one component. In this connection the intention of the project is to minimize the complete frame size, get a highly cost‐efficiency and analysing the EMI behaviour of the whole converter. Summarized the intension of the project is to increase the operation efficiency of this PFC‐converter.

The described subproject will be realised on the laboratory of Power Electronics on the University of Applied Sciences in Augsburg which is led by Prof. Dr. Manfred Reddig. The Institute for Electrical Drive Systems and Power Electronics of the Technische Universität München under Univ.‐Prof. Dr. Ralph Kennel is the cooperating partner of this project which is performed by the University of Applied Sciences in Augsburg.
