METHOD FOR DETERMINING AN ELECTRICAL PARAMETER AND MEASUREMENT ARRANGEMENT FOR DETERMINING AN ELECTRICAL PARAMETER

摘要

A method for determining an electrical parameter comprises charging, in parallel, a first and a second capacitor (CL1, CL2) from a common supply voltage (VL). Then, a first discharge time (t11) is determined by discharging the first capacitor (CL1). Furthermore, a second discharge time (t12) is determined by discharging the first capacitor (CL1) a second time or by discharging the second capacitor (CL2). Finally, the electrical parameter is determined from a ratio of the first and the second discharge times (t11, t12).
