Abstract: The invention relates to a method for measuring the output current of a clocked half-bridge circuit (1) in which semiconductor switches (5a, 5b) located in half-bridge sections (2a, 2b) are alternatingly opened or closed in push-pull operation and thereby cause an alternating current in an output current circuit. The current flowing through a first semiconductor switch (5a) is measured. The current flowing through a first semiconductor switch (5a) is transformed inductively into a secondary current. At least two measured-value signals are generated for the secondary current, of which a first measured-value signal corresponds to the secondary current when the first semiconductor switch (5a) is closed, and a second measured-value signal corresponds to the secondary current when the first semiconductor switch (5b) is open. The output current is determined by taking the difference between the first and second measured-value signals FIG. 7.

Abstract: A measuring device for measuring an electrical current has an alternating-current converter (6) that possesses a primary inductance and an ohmic secondary resistance (RS) and whose output is connected across a measured-value signal conditioning device to a measurement output for a current measuring signal. The output of the alternating-current converter (6) has an ohmic secondary resistance (RS). An active compensation circuit, which at least partially compensates for the voltage drop caused by a current flow in the secondary resistance (RS) at the primary inductance by applying a voltage at the output of the alternating-current converter (6), is disposed between the output of the alternating-current converter (6) and the measurement output.
