CIRCUIT ARRANGEMENT AND OPERATING METHOD |
| 摘要 |
A circuit arrangement (1) for operating an electric machine. The circuit arrangement (1) includes at least one high-voltage half-bridge circuit (2), which has a high-side semiconductor switch (3) and a low-side semiconductor switch (4). In each case one gate driver (5, 6) is assigned to the semiconductor switches (3, 4) for actuating said semiconductor switches, and includes a low-voltage controller (7), which actuates the gate drivers (5, 6). A high-voltage controller (11) senses output signals (AS) of the gate drivers (5, 6) and transmits at least the sensed output signals (AS) to the low-voltage controller (7) using a data bus (12). |
