摘要： In a boost converter operation, a first voltage that is independent of an input voltage of the boost converter is preset in the boost converter, having an increased voltage level compared to the input voltage, as the setpoint output voltage, as long as the input voltage is below a first voltage threshold value, which is lower than the first voltage. As soon as the input voltage exceeds the first voltage threshold value, a second voltage that is a function of the input voltage is preset, having a lower voltage level compared to the input voltage, as the setpoint output voltage. As soon as the input voltage drops below a second voltage threshold value, which is lower than the first voltage, the first voltage is again preset as the setpoint output voltage.

摘要翻译： 在升压转换器操作中，与升压转换器的输入电压无关的第一电压被预置在升压转换器中，与输入电压相比具有增加的电压电平作为设定点输出电压，只要输入电压 低于第一电压阈值，其低于第一电压。 一旦输入电压超过第一电压阈值，则预设与输入电压相比具有较低电压电平的作为输入电压的函数的第二电压作为设定点输出电压。 一旦输入电压下降到低于第一电压的第二电压阈值，则第一电压再次被预设为设定点输出电压。

摘要： A device and a method for detecting a polarity reversal on a low voltage side of a DC voltage transformer in a dual-voltage vehicle electrical system, particularly in a motor vehicle. A current flow is enabled, in this instance, in a connecting line on the low voltage side of the DC voltage transformer by a controllable switching element, a current is detected in a connecting line on the low voltage side of the DC voltage transformer, with the aid of a current sensor system, the direction of the detected current is evaluated by an evaluation unit and a polarity reversal is detected if the direction of the detected current differs from an expected current direction.
