Circuit for measuring discharge time of capacitor, has capacitor unloaded by low impedance switching of electronic switches, and measuring resistor connected with charge electrode of capacitor through electronic switches

摘要

The circuit (1) has a charge electrode of a capacitor connected with a voltage source for charging. The capacitor is unloaded through measuring resistors (2.1-2.4) by low impedance switching of electronic switches (AS1-AS4) i.e. analog switches. One of the measuring resistors is connected with a charge electrode of the capacitor through the electronic switches. A counter electrode of the capacitor and the electronic switches are grounded and facing away from a connection of the measuring resistor. An independent claim is also included for a method for measuring discharge time of a capacitor through a measuring resistor.
