BIDIRECTIONAL DC CONVERTER WITH BUFFER CAPACITOR AND CONTROLLABLE VOLTAGE AT THE CAPACITOR

摘要

A bidirectional DC-to-DC converter is configured to convert electrical energy from a first and second DC source. The bidirectional converter includes an output capacitor providing an output voltage and a first and second inductor. The first inductor is arranged between a positive connection of the second DC source and a first contact of a first switch. The second inductor is arranged between a negative connection of the first DC source and a second contact of the first switch. A buffer capacitor is arranged between a negative output of the first DC source and a positive output of the second DC source. A second and third switch are arranged in series with the first switch. The second switch is arranged between the first contact of the first switch and the positive DC output. The third switch is arranged between the second contact of the first switch and the negative DC output.
