This paper described new working mode of Power Factor Corrector (PFC), called Boundary Continuous Mode (BCM); studied the design parameters of the critical components for the BCM-PFC in the boost topology; proposed a method and a tool for designing an L6562A-based BCM-PFC Boost Converter. The method and tool was verified on an evaluation board emulating a PFC boost converter with an 80W output power, 400Vdc output voltage and a wide range main input from 85Vac to 264Vac; and it can be easily adapted for applications with higher output power around 400W.

It is widely considered that standardization is an important means for information processing£¬exchanging£¬managing and clearing up technical bulwark more effectively. The paper studies the theoretics and methods about the E-HUB platform. After analyze business environment in Southwest China, a generic conceptual framework will be developed and a prototype implementation of the generic concepts will be benchmarked in system design of manufacturing information system. The small and medium-sized enterprises (SMEs) can solve their complex project tasks and participate in projects far exceeding their individual capabilities.

Mobile e-commerce systems are the big trend of international economy and social development now days, and also the key process of industry upgrade, industrialization and modernization in our country. Mobile e-commerce systems are considered as the backbone of the manufacturing industry in China, Vulnerabilities in web applications continue to be the most frequently discovered security problem. This article illustrates a trusted operating systems how to provide a flexible solution to the problem of application for e-commerce. With the help of Chinese Wall, web services are becoming popular in Web applications. In the end, we present strategies for e-commerce application: trusted e-commerce module.

E-Hubs as new entrants with new business models pour into the business-to-business space; it's increasingly difficult to make sense of the landscape. Electronic hubs--Internet-based intermediaries that host electronic marketplaces and mediate transactions among businesses--are generating a lot of interest. This paper provides a blueprint of the E-Hubs arena. Conceptual specification of functional system, comprising the selection of core E-Hubs services and definition of basic hosting platform of the E-Hubs realization business development plan, Conceptual framework for Manufacturing Resource Management System designs based on E-hubs.
