Our team designed a 3.25kW DC/DC converter (from 50V–100V input to 280–400V output) to charge a LiPo battery from a polymer electrolyte fuel cell for unmanned autonomous vehicle applications. After research and simulation of several boost converter topologies and integrated circuits, we proposed a non-isolated and isolated push-pull design. The push-pull design was favored due to its high efficiency, ease of digital control, and compliance with our design criteria. Our schematic facilitates the design and testing of a PCB layout of the converter in the future.
