Claim Text:
1. A method for activating a rectifier, which has active switching elements, the method comprising: activating the active switching elements of the rectifier during a voltage clamping so that a clamp voltage in each switching branch of a corresponding one of the active switching elements complies with a ramp-shaped change in a signal form predefined as a function of time within each half-period of a current to be rectified; wherein the ramp-shaped change in the clamp voltage is in each of the switching branches within a corresponding one of each half-wave of the voltage clamping for each of the active switching elements, and wherein power converted during the voltage clamping during a load dump is distributed to each of the active switching elements of the switching branches so that substantially homogeneous heating occurs for each of the active switching elements.
