New control methods for rectifier-less PFC-stages

The paper describes a new PFC topology with a reduced number of rectifier stages. The proposed converter is capable to deliver an output power of 2 kW. Simplified voltage and current measurement circuits are implemented. The static and dynamic behaviour of the converter using a new Infineon control IC is shown.
