Abstract
A circuit arrangement () for operating an electric machine. The circuit arrangement () includes at least one high-voltage half-bridge circuit (), which has a high-side semiconductor switch () and a low-side semiconductor switch (). In each case one gate driver () is assigned to the semiconductor switches () for actuating said semiconductor switches, and includes a low-voltage controller (), which actuates the gate drivers (). A high-voltage controller () senses output signals (AS) of the gate drivers () and transmits at least the sensed output signals (AS) to the low-voltage controller () using a data bus ().
