Design recommendations for future household devices concerning their high frequency emission in the range between 2 kHz and 150 kHz

Abstract

In order to reduce the high frequency (HF) disturbances in the frequency range of 2 kHz to 150 kHz, recommendations for the design of future active power factor correction (PFC) circuits that are used in typical household devices are presented in this paper. The design recommendations are based on laboratory measurements which are performed on two PFC circuits with different switching frequencies and on an interleaved PFC circuit with varying switching frequency. Here, two different scenarios are considered (with and without classical designed grid side filter). Additionally, the two topologies of these PFC circuits and the corresponding control strategies are described in detail regarding the HF emission characteristics.
