1. A DC/DC converter circuit, comprising:
at least two DC/DC converters; and a low-pass filter; wherein the DC/DC converters in each case have one input side and one output side, and the DC/DC converters are connected to each other in series on the output sides, and wherein the low-pass filter is post-connected to the DC/DC converters which are connected in series to one another, and wherein the low-pass filter smoothes the output voltage generated by the DC/DC converters at the output sides of the DC/DC converters; wherein at least one of the DC/DC converters includes a primary circuit and a secondary circuit, the primary circuit having a primary-side transformer coil and the secondary circuit having a secondary-side transformer coil, and the primary-side transformer coil and the secondary-side transformer coil are connected to each other to form a transformer; and wherein:
the primary circuit includes an H-bridge circuit having a first branch going from a first node to a second node, the first branch including a first battery module, a second branch going from a first node to a second node, the second branch including a second battery module, and a bridge branch lying between the first branch and the second branch, the first node being positioned between the first and second battery modules;the primary-side transformer coil is situated in the bridge branch;in the first branch, a first switch and a first terminal for the connection of the first battery module are situated; andin the second branch, a second switch and a second terminal for the connection of the second battery module are situated. |
