Energy supply system for high-frequency drone reluctance switched motors with multi-cell converters and space-timemodulationвачами і просторово-часовою модуляцією

Drones are widely used to solve many practical problems. The main parameters of drones are flight range, load capacity, speed and shunting characteristics. Currently, the best technical characteristics are drones with permanent magnet motors and lithium-polymer batteries. Placing more pairs of poles on the rotor reduces the size of the motor while maintaining the same torque, but requires the use of more complex, spatio-temporal laws of voltage modulation and multichannel power converters, which slightly increases the weight of the power supply system. not used in practice. The proposed design of switched reluctance motor has a much lower weight due to the operation at high frequencies, which reduces the weight of the motor several times. The purpose of the development is to improve the technical performance of drones: flight range, load capacity due to the improvement of electrical and electro-mechanical systems; sharing several energy sources. The tasks to be solved by the research include: development of the topology of the converter with bidirectional energy transfer and increased current transfer for the combined energy source battery-supercapacitor; analysis and development of new multi-cell topologies of power converters and algorithms for their control for the formation of spatio-temporal modulation of the supply voltage of windings; the choice of structure and implementation of the proposed design of switched reluctance motor, operating at an intermediate high frequency; coordination of modes of operation of power sources and the engine and ensuring their electromagnetic compatibility.
