ABSTRACT:
Disclosed is a method for diagnosing a half-bridge having a first and a second switching element. The method includes providing a half-bridge that has a first and a second switching element connected in series with each other. The first and the second switching element are driven on and off cyclically, with the switching elements during one drive cycle being alternatingly driven on and off such that they are alternatingly subject to a load current flowing therethrough. A current measuring signal is provided, representing a current flow through one of the switching elements. A first reference signal is provided. A first diagnostic signal is generated that is dependent on an integral of the measuring signal over a first integration period, and on an integral of a first reference signal over a second integration period.
