Aiming at product information management in modern enterprise, the warehouse management system in this paper uses the J2EE architecture and is based on B/S mode. It uses SSH, the more popular integrated open-source framework in web application, improves the security and reliability of the system. This paper mainly introduces architecture and database design of the system. The design of user permissions...
The structure of switched reluctance motor for the hybrid vehicles is shown firstly in this paper. Basing on the mechanical characteristics and the electrical characteristics, in order to optimize the drive system efficiency, reduce the noise and torque ripple, upgrade the capability of output, three different control strategies are proposed in the paper. Current chopping control, voltage chopping...
This paper briefly mentions the micro controller unit, and then goes into details about the exact regulations for SRM. Firstly, it proposes the main driving state control for motor and the importance of the motor position sensor. For different speed, the controller will choice various styles such as voltage chopper control, angle position control and current chopper control for which owns its advantages...
This paper introduces the parameter designing of the DC hybrid circuit breaker (CB). In the CB, the current limiting circuit is designed to inhibit the increasing of fault current, the combinatorial electronic power switch is designed to reduce the series connecting number of power electronic device. And also the process of energy release and the configuration method of the combinatorial switch are...
