Abstract
The present disclosure relates to a method and a corresponding circuit for the fault detection of an electrical circuit, wherein the electrical circuit includes a first inductive interface, at least a first branch, and a second branch, wherein the first and the second branches are connected in parallel, wherein the first branch includes two parallel and counter-currently-connected diodes, and wherein the first and second branches are connected to the first inductive interface. The method includes applying an alternating voltage or an alternating current across the first inductive interface via a second inductive interface, wherein the applied voltage or current is low enough that essentially no current flows through either the first or the second diode; measuring the impedance across the first inductive interface via the second inductive interface; and determining whether a fault is present in the second branch.
