CIRCUIT CONFIGURATION FOR THE DISCHARGE CONTROLLED BY MEANS OF A CONTROL UNIT OF A CAPACITOR FROM A HIGH VOLTAGE TO A LOW VOLTAGE |
摘要 |
<p>The object is to discharge a first capacitor from a high voltage to a low voltage. To this end, the one electrode of the first capacitor is linked with the one electrode of a second capacitor via a FET path. The other two electrodes of the two capacitors are connected to reference potential. A voltage source with its internal resistance is connected in parallel to the second capacitor. A discharge path leads from the one electrode of the first capacitor from the paths of two FET and a protective resistor to the reference potential. A current path leads from the one electrode of the second capacitor to the reference potential via the paths of two additional FET. A control unit switches on the discharge path. Once the voltage of the first capacity has decreased to the required lower value, the discharge path is blocked while a holding path is opened.</p> |
