Abstract

UAVs have the advantages of long endurance, remote operation, high load capacity, high reliability, etc. Its airborne energy power system is the key core technology of the aircraft platform. Based on the research on the electrical power supply system of UAVs, a starter/generator module for the hybrid power system is designed in this paper. This module has functions such as engine electric starter, power generation, secondary power supply, uninterrupted circuit, status monitoring, fault detection and so on. Through the modeling and simulation of permanent magnet brushless DC motor system and the hardware and software circuit design based on TMS320F28035 control chip, the Principle Prototype of starter/generator module was developed. The experimental results show that the module can work normally and achieve its function. That means hybrid UAV starter/generator module has good performances.
