Abstract
The invention relates to a method for modulating the boost converter operating mode of a push-pull converter having a low-voltage-side circuit, having a first low-voltage-side switching device and a second low-voltage-side switching device; having a transformer having a high-voltage-side winding; and having a high-voltage-side circuit, which is configured as a full-bridge rectifier, having a first and a second rectification element which form a first half-bridge and a third and a fourth rectification element which form a second half-bridge; wherein the method comprises the steps of closing the first low-voltage-side switching device while simultaneously short-circuiting the high-voltage-side winding via the first or the fourth rectification element during a first time segment; opening the rectification element used for short-circuiting the high-voltage-side winding during a second time segment; opening the first low-voltage-side switching device and closing the second low-voltage-side switching device while simultaneously short-circuiting the high-voltage-side winding via the third or the fourth rectification element in the second half-bridge during a third time segment; and opening the rectification element used for short-circuiting the high-voltage-side winding during a fourth time segment.
