摘要： The present invention relates to the control of a DC-DC converter, wherein the gradient of a controlled variable is limited for the control of the DC-DC converter. A maximum current change in the DC-DC converter can be limited by limiting the gradient of the controlled variable in order to optionally prevent dangerous operating states of the DC-DC converter.

摘要： The present invention relates to advanced control for a DC-to-DC converter. For this purpose, in the determination of a controlled variable for the control of the DC-to-DC converter, the control dynamics are adjusted according to an electric current through the DC-to-DC converter. In particular, it is possible to determine the controlled variable from a combination of a first controlled variable of a voltage controller and a second controlled variable of a feedforward control. In particular, the control dynamics of the feedforward control can be adjusted according to the electric current through the DC-to-DC converter. By adjusting the control dynamics according to current, it is possible to minimize possible current ripple on the output side.

摘要： The invention relates to a method (100) for charging an intermediate circuit capacitor (210) in a high-voltage network (205). The high-voltage network can be connected to a power source (220) by means of at least one switch (230) and is coupled to a low-voltage network (295) by means of a DC voltage converter (250). The method comprises the steps: determining (110) a first voltage (U1) across the power source (220); determining (120) a second voltage (U2) across the intermediate circuit capacitor (210); determining (130) a first difference (D1) between the first voltage (U1) and the second voltage (U2); switching (140) the DC voltage converter (250) to the boost converter operating mode to charge the intermediate circuit capacitor (210) according to the determined first difference (D1).

摘要： The present invention relates to a control of a DC converter (10) comprising a plurality of DC converter modules (4-1, 4-2). For this purpose, a central control variable is generated for all DC converter modules for a voltage-controlled control of the DC converter. Moreover, a current-based control variable can additionally be generated for each DC converter module. The output power, in particular the output current of each DC converter module can be individually adjusted by combining the voltage-based control variable and the current-based control variable. An overload of the DC converter modules can thus be prevented.

摘要： The invention relates to control of a DC converter having multiple parallel-connected DC converter modules. Here, a common variable for the voltage control is formed for the control of all the DC converter modules. In addition, a separate current controller is provided for each DC converter module. For each DC converter module, a control variable can be formed from the individually determined current control and the jointly determined voltage control.

摘要： The invention relates to a control system for a DC-to-DC converter. Variations in the input voltage of the DC-to-DC converter are compensated by means of an estimated value being calculated for the variations, and a control variable being determined for the DC-to-DC converter based on the estimated values of the input voltage. The estimated values for the input voltage can, for example, be determined on the basis of a polynomial, for example using a Lagrange expansion.
