Abstract: A method for operating a power factor correction circuit is provided which may include the steps of providing a plurality of N switched-mode converter circuits each comprising an nth inductor, where N is at least 2, starting a switching pulse for the nth switched-mode converter circuit when the following conditions are fulfilled: the nth inductor of the nth switched-mode converter circuit has a predefined magnetization state; and a predefined time period has elapsed since the start of a switching pulse for an mth switched-mode converter circuit, where m=n−1 in case n>1 and m=N in case n=1. The predefined time period is a predefined fraction of the time period from the start of a previous switching pulse for the nth switched-mode converter circuit to a time when the nth inductor of the nth switched-mode converter circuit has the predefined magnetization state.

Abstract: In one example, a method includes outputting, during a first phase, a first current level at a connector, and outputting, during a second phase, a second current level at the connector, wherein the second current level is complementary to the first current level. In this example, the method also includes determining whether or not a voltage level of the connector satisfies a threshold, and responsive to determining that the voltage level of the connector satisfies the threshold, determining that the connector is floating.
