A bridge rectifier having AC voltage terminals, two DC voltage terminals, and a number of half-bridges corresponding to the number of AC voltage terminals. Each half-bridge has two activatable switching elements, connected in series between the DC voltage terminals and between which one of the AC voltage terminals is connected in each case. Each half-bridge includes a control circuit configured to detect an output voltage applied between the DC voltage terminals and switch a first switching element of the two switching elements of the particular half-bridge to be conductive by activation using a first control signal until the output voltage falls below a lower threshold value, after it has previously exceeded an upper threshold value, and to activate it in a clocked manner by activation using a second control signal, until the output voltage exceeds the upper threshold value, after it has previously fallen below the lower threshold value.
