Abstract: In some aspects, an actuation system includes an electrical positioning driver and an electrically-driven actuator. A voltage boost converter in the electrical positioning driver receives an input voltage. The voltage boost converter passes the input voltage to a voltage bus in the electrical positioning driver. The voltage on the voltage bus is converted to an actuator power signal that controls the electrically-driven actuator. The voltage boost converter boosts the voltage on the voltage bus to control a mechanical output performance of the electrically-driven actuator.

Abstract: This disclosure generally relates to a hybrid solid-state propulsion system for aerial vehicles. The hybrid propulsion system includes a combustor, a thermophotovoltaic generator, and a thermoelectric generator. The combustor burns a chemical based fuel to produce radiation and heat that are converted into electricity used to power the aerial vehicle. The thermophotovoltaic generator is positioned to receive radiation and remnant heat generated by flames in the combustor while the thermoelectric generator receives heat from exhausted flue gases from the combustor.

Abstract: A circuit disconnection element that can open or short-circuit between a power storage element and a step-up/step-down bidirectional chopper circuit is provided in a power storage system, thereby preventing a self-discharge state in a process of charging. Furthermore, at the time of occurrence of an abnormality, the power storage element is detached from other devices including the step-up/step-down bidirectional chopper circuit. Accordingly, an energy loss of the power storage element at the time of power regeneration can be reduced to improve the energy use efficiency. Further, breakage influences such that the power storage element causes breakage in other devices at the time of occurrence of the abnormality can be prevented, thereby enabling to obtain an AC motor drive device having mounted therein a highly safe power storage system.
