| 摘要 |
The invention relates to a method for measuring an insulation resistance and to an inverter comprising a device for measuring an insulation resistance. A central point (5) which lies between the switching elements (3, 4) of a half-bridge (2) of the inverter (1) is connected to a grounding point (15) by closing a grounding switch (14). The central point (5) connected to the grounding point (15) is successively connected to the two ungrounded poles (20, 21) of an inverter (1) intermediate circuit voltage, which is applied to the half-bridge, by means of the switching elements (3, 4) of the half-bridge (2), and the current flowing to the grounding point (15) via said connection is measured. |
