AI Technical Summary

Technical Problem

The boost circuits of existing electric aircraft require modifications to the original motors or the addition of components, which increases circuit complexity and size, violates the principles of lightweight and miniaturization design, and may reduce reliability.

Method used

By configuring any one phase of the motor's three-phase windings as the input winding and the other windings as auxiliary windings to form an energy storage inductor, the voltage boost function can be achieved by using the inverter's controllable switch to control the conduction and cutoff of the auxiliary windings, thus avoiding the need to modify the motor or add components.

Benefits of technology

It achieves boost functionality without increasing hardware size and weight, maintains the reliability of electric aircraft, and reduces current ripple and thermal management requirements by reusing existing components.

Abstract

本发明公开了一种升压控制方法、系统、装置及电动航空器,该升压控制方法用于控制电机和逆变器,通过将电机的三相绕组配置为储能电感,并控制逆变器中对应的可控开关的导通和关断,以实现升压功能。由于电机、逆变器均为复用电动航空器原有组件,无需改造电机增设中性点接口或增设电感,且逆变器、电机和高压电池的连接方式为电动航空器原有连接方式,仅改变逆变器的控制逻辑,所以不会增大原有电动航空器的硬件体积和重量,同时也不会增加新的故障点,实现升压功能的同时不会降低电动航空器的可靠性。
