In this paper, the computer aided design, analysis, optimization and manufacturing processes of switched reluctance machine (SRM) with a piece of self-developed software are detailed presented. According to the performance requirements, the physical dimensions of stator and rotor laminations are obtained by two traditional methods. Then, the electromagnetic characteristics and operating performances...
Aiming at the requirement of synchronous multichannel data acquisition in large-scale acquisition netwrok, it presents a distributed measurement and control system that is based on EtherCAT with real-time ethernet technology and distributed clock. It ensures the synchronization, timeliness and ordering of the system. And the board-level data synchronization acquisition was implemented by device selection...
The basic concepts and advantages of more/all electric aircraft (M/AEA) are briefly addressed. The combined starter/generator (CS/G) system is introduced as a key technology to enable M/AEA. Some important performance requirements for CS/G system are obtained. Based on these requirements, a high speed switched reluctance machine (SRM) is designed to operate as a starter/generator. The entire design...
The application background and operating principle of the Switched Reluctance Starter/Generator (SR S/G) system are briefly introduced. The structure and technical parameters of an undergoing 30 kW Switched Reluctance Machine (SRM) and its converter are described. Based on these works, the thermal analysis of the SRM and its converter are presented in detail. The transient lumped-parameter thermal...
Some general considerations for the design of the power converter used in an undergoing 30 kW switched reluctance starter/generator system are presented. The most suitable converter topology and power semiconductor are found firstly based on features of the application and comparisons among many possibilities. Then, the frequency stress, voltage ratings, peak and rms current ratings of the power semiconductor...
