Abstract

A rectifier bridge circuit is described for rectifying the phase voltage generated by a generator, including a positive half-bridge having multiple rectifier elements and a negative half-bridge having multiple rectifier elements. The rectifier elements each have a controllable switch having a diode connected in parallel. A control circuit is provided for switching the switches on and off. The switch-on time tswitch on setpoint and/or the switch-off time tswitch off setpoint of the switch is/are computed based on a characteristic map or a mathematical function.
