US 11,764,680 B2 · Control device for a DC-DC converter and method for the closed-loop control of a DC-DC converter

Abstract

The invention relates to enhanced adjusting of the control variables for a DC-DC converter comprising multiple DC-DC converter modules (30-1, 30-2). For this purpose, alongside the conventional controlling of the individual DC-DC converter modules, an additional correction variable (K-1, K-2) is determined which can be added to the control variable (R4-1, R4-2). In particular, the correction variable can take into account individual properties of the DC-DC converter modules, such as component tolerances or similar. For this purpose, correction values suitable for the individual DC-DC converter modules can be determined in advance and stored in a non-volatile storage means. Using these previously stored links, the control variables for the individual DC-DC converter modules can be individually adjusted.

A control device for a DC-DC converter (1) having a plurality of DC-DC converter modules (30-i), the control device comprising:

a control unit (10) configured to provide, for each DC-DC converter module (30-i), an individual controlled variable (R4-i) using a setpoint variable for the output voltage, a measured value of an output voltage, a measured value of an input voltage and a measured value of respective current in each DC-DC converter module (30-i);
a compensation unit (20) configured to provide, for each DC-DC converter module (30-i), a compensation variable (K-i) using the individual controlled variable (R4-i) for the respective DC-DC converter module (30-i) and a prestored correction value,
wherein each DC-DC converter module (30-i) is driven using a combination of the respective individual controlled variable (R4-i) and the corresponding compensation variable (K-i).
