This class of UAV depends on solar power to meet its long flight time requirements. Solar power systems rely on the use of maximum power-point tracking (MPPT) circuitry to ensure that solar energy is harvested at the optimum voltage before conversion to a voltage suitable for charging a secondary battery, or delivery to the power systems intermediate bus network. As this class of UAVs develops, high-efficiency power-conversion topologies such as zero-voltage switching and zero-current switching (ZVS/ZCS) which are used in Vicor BCMs are important to enable the widening variety of fuel sources and applications with increasing power challenges.
A combination of the BCM6123 providing the isolated conversion of the 350V to a 48V intermediate bus and the PI3741 ZVS Buck-Boost regulator with a very wide range input voltage operating capability provides a tightly regulated 28V output for various UAV loads.

Where fixed-ratio converters fit in high-power delivery systems
The density and efficiency of a fixed-ratio converter plays a critical role in enabling PDN architecture to deliver high performance
Life-saving tethered drones get a power and comms boost
The initial DC-DC converter design was heavy & consumed too much space. The lightweight DCM by Vicor provided the ideal power & weight for the application
