Circuit for measuring and limiting currents in converters for supplying motors |
摘要 |
A current measuring device (21) is connected directly in series with a capacitor (10) in an intermediate circuit (4), so that only the capacitor current flows through it. A device such as an NTC resistor may be connected in series with the capacitor for limiting switch-on current when the intermediate circuit is connected to the mains with a discharged capacitor, only the capacitor current flows through the limiting device. |
