Multiphase/Multi-unit Generator Rectifier Control Strategy for Aviation High Voltage Generation System
摘要
With the development of more electric/all electric aircraft, the use of electricity in airborne equipment has increased, leading to a trend towards more comprehensive integration. High-voltage DC power generation system has the characteristics of high capacity and high efficiency, which offers obvious advantages in aviation DC power generation system. Multiphase/Multi-unit motor have clear advantages in the field of large capacity power generation. By using existing power tubes of a certain level, which can achieve large capacity power transformation. Compared to three phase motor, they offer advantages such as larger capacity, higher reliability, and greater control flexibility. As the primary components of aviation power systems, aviation generator and rectifier combine to form an aviation high-voltage generation system. Due to the high speed of the aviation generator and varying DC bus loads, the output voltage of the aviation rectifier is not fixed, requiring a rectifier control strategy that adjusts the contribution according to real-time feedback voltage and current to maintain either constant load-side power or a constant voltage. This thesis explores the control strategy of a multiphase/multi-unit permanent magnet synchronous generator rectifier system, and completes the algorithm validation of the rectifier system of the high-voltage generator.
