Abstract: A power conversion unit may include two or more power modules for providing high-voltage direct current power to electrical loads, such as one or more propulsion motors aboard an aerial vehicle. Each of the power modules may be controlled by hysteresis, and may include one or more pairs of transistors that are switched by a gate driver with respect to differences between a reference current and a sensed current passing through a boost inductor. The number, size and shape of the power modules may be selected to accommodate the electrical loads, and may be switched on or off, as necessary. The power conversion unit may feature at least one more power module than is required to meet all anticipated electrical loads, thereby ensuring that the power conversion unit may continue to provide power even in the event that one of the power modules experiences a fault of any kind.

Abstract: The zero carbon emission vehicle as disclosed herein may include a condenser for extracting fluid water from the atmosphere, an electrolyzer for generating hydrogen from the fluid water, and one or more deformable fluid-retaining chambers that couple thereto for selectively adjusting the buoyancy and altitude of the zero carbon emission vehicle in real-time, to maintain the air vehicle in flight substantially without needing to land and refuel the air vehicle. Solar panels provide the energy for the described systems, and the energy from the solar panels can be stored in the form of hydrogen gas which gives buoyancy to the air vehicle.
