摘要： The invention relates to a rectifier module (40) for an active bridge rectifier, said module comprising two switch elements which are serially connected between two end terminals and between which a central tap is formed and comprising an actuation circuit with a monitoring unit (43), a synchronization unit (41), and an actuation unit. The monitoring unit (43) is designed to detect a measurement voltage and output a request signal if the measurement voltage exceeds an upper threshold. The synchronization unit (41) is designed to output a synchronization signal at a synchronization terminal (c) as long as the monitoring unit (43) outputs the request signal and to otherwise monitor the synchronization terminal (c) for a synchronization signal. The actuation unit is designed to at least partly switch one of the two switch elements to the conductive state during an actuation period if the monitoring unit (43) outputs the request signal and/or if the synchronization signal is detected by the synchronization terminal (c) monitoring process and optionally recognized as a valid synchronization signal. The invention likewise relates to an active bridge rectifier with corresponding rectifier modules (40), to a generator arrangement with such a bridge rectifier, to a corresponding motor vehicle electrical system, to a corresponding operating method, and to means for implementing said operating method.

摘要： A method for driving a bridge rectifier (1) with active switching elements (S) is proposed, in which, during normal operation, at least one of the active switching elements (S) is driven using a voltage signal, the voltage of which is changed from a first voltage value to a second voltage value within at least one switching time, wherein, if load shedding at the bridge rectifier (1) is determined, the at least one switching time is extended by a predefinable period. The invention likewise relates to a corresponding rectifier arrangement and to a computer program product.

摘要： The invention relates to a method for operating an active rectifier (4) that comprises a plurality of actuatable semiconductor switch elements (AH-EH, AL-EL), in which a first actuation mode (M1) and a second actuation mode (M2) are switched between and vice versa in order to actuate said semiconductor switch elements (AH-EH, AL-EL). In the first actuation mode (M1), the semiconductor switch elements (AH-EH, AL-EL) are actuated with a first switching time and, in the second actuation mode (M2), they are actuated with a second switching time, the second switching time being greater than the first switching time, and said method comprising the following steps a) to c) and/or d) to f): a) acquiring a starter variable value of an electrical starter variable for said rectifier, b) comparing the starter variable value to a comparative value, c) switching from the first actuation mode (M1) to the second actuation mode (M2) if the starter variable value is greater than said comparative value, d) acquiring an operational variable value of an electrical operational variable of one of the semiconductor switch elements (AH-EH, AL-EL), e) comparing the operational variable value to a comparative value, and f) switching from the second actuation mode (M2) to the first actuation mode (M1) if the operational variable value is greater than said comparative value. The invention also relates to a corresponding circuit arrangement (2), and to a computer program.

摘要： The invention relates to a bridge rectifier, which comprises a number of alternating-voltage connections (u), two direct-voltage connections (B+, B–), and a number of half bridges that corresponds to the number of alternating-voltage connections (u). Each half bridge has two controllable switching elements (S1, S4) connected in series between the two direct-voltage connections (B+, B–), between which two switching elements one of the alternating-voltage connections (u) is connected. Each half bridge also comprises a control circuit (4U), which is designed to detect an output voltage present between the two direct-voltage connections (B+, B–) and to switch a first switching element (S1, S4) of the two switching elements of the respective half bridge to the conductive state by controlling the first switching element by means of a first control signal until the output voltage falls below a lower threshold value after the output voltage has previously exceeded an upper threshold value, and to control the first switching element in a clocked manner by controlling the first switching element by means of a second control signal until the output voltage exceeds the upper threshold value after the output voltage has previously fallen below the lower threshold value. According to the invention each control circuit (4U) has threshold value elements (A2), which are designed to effect a change in the lower and/or upper threshold value after the output voltage has previously exceeded the upper threshold value. The invention further relates to an associated operating method and to means for implementing said operating method.

摘要： The invention relates to a method for operating an on-board power supply of a motor vehicle, said on-board power supply having an electrical motor that can be operated in a power-generating manner and a bridge rectifier that is connected to the electrical motor via phase connections, and which power supply can be operated in a rectifier operating mode and in a short circuit operating mode. After the bridge rectifier has been operated at least once in a short circuit operating mode in a first method phase, the method comprises, inter alia, the step of determining, on the basis of at least one characteristic of a signal indicating a drop in voltage between the DC voltage connections of the bridge rectifier, whether the signal of the upper threshold value has been exceeded as a result of a cable breakaway at at least one of the DC voltage connections. In the above-mentioned case, in a second method phase, the bridge rectifier is subsequently operated in the short circuit operating mode for an extended period of time, and/or, in the second method phase, a control signal having a second switching time greater than that in the first method phase is used, in order to control the active switching elements. The invention also relates to means for carrying out a corresponding method.
