Claim Text:
1. A bidirectional DC-to-DC converter for converting electrical energy from a first DC source and a second DC source, comprising: an output capacitor configured to provide an output voltage, wherein a positive contact of the first DC source is connected to a positive DC output of the bidirectional DC-to-DC converter and a connection of the output capacitor, and a negative contact of the second DC source is connected to a negative DC output of the bidirectional DC-to-DC converter and the second connection of the output capacitor; a first and a second storage inductor, wherein the first storage inductor is arranged between a positive connection of the second DC source and a first contact of a first electronic switch, and wherein the second storage inductor is arranged between a negative connection of the first DC source and a second contact of the first electronic switch; a buffer capacitor arranged between the negative output of the first DC source and the positive output of the second DC source; a second electronic switch and a third electronic switch arranged in series with the first electronic switch, wherein the second electronic switch is arranged between the first contact of the first electronic switch and the positive DC output, and the third electronic switch is arranged between the second contact of the first electronic switch and the negative DC output, wherein by switching on and off the first, second or third electronic switch, a differential voltage across the buffer capacitor can be regulated, and a first DC current of the first DC source and a second DC current of the second DC source from the first and second DC source to the DC output or from the DC output to the first and second DC source can be set.
