Abstract
The invention relates to a circuit arrangement (), in particular for controlling an electric machine, comprising at least one high-voltage semiconductor bridge circuit () that includes a low-side semiconductor switch () and a high-side semiconductor switch (). A high-side gate driver () is assigned to the high-side semiconductor switch (), and a low-side gate driver () is assigned to the low-side semiconductor switch (). According to the invention, a high-side flyback converter () is connected upstream of the high-side gate driver, and a low-side flyback converter () is connected upstream of the low-side gate driver (), at least one of the flyback converters () being designed as a high-voltage flyback converter.
