  • Flexible power conversion systems with wide DC voltage utilization
    Patent number: 10985659
    Abstract: A DC-DC power converter comprises: first, second and third input nodes for connection to one or more DC input power sources; a pair of upper switches TH1, TH2 connected in series between the first and second input nodes; and a pair of lower switches TL1, TL2 connected in series between the second and third input nodes. An output port is connected, via one or more output capacitors and one or more output inductors, to an upper switching node between the pair of upper switches and a lower switching node between the pair of lower switches TL1, TL2. The converter is connectable to a pair of DC input power sources, with a first DC input power source connected between the first and second input nodes and a second DC input power source connected between the second and third input nodes, and, when so connected, the pair of upper switches TH1, TH2 and the pair of lower switches TL1, TL2 are switchable to provide DC output power at the output por.
