  • 基于IR2101最大功率跟踪逆变器的设计

    为解决直流逆变交流的问题,有效地利用能源,让电源输出最大功率,设计了高性能的基于IR2101最大功率跟踪逆变器,并以SPMC75F2413A单片机作为主控制器。高电压、高速功率的MOSFET或IGBT驱动器IR2101采用高度集成的电平转换技术,同时上管采用外部自举电容上电,能够稳定高效地驱动MOS管。该逆变器可以实现DC/AC的转换,最大功率点的跟踪等功能。实际测试结果表明,该逆变器系统具有跟踪能力强,稳定性高,反应灵敏等特点,该逆变器不仅可应用于普通的电源逆变系统,而且可应用于光伏并网发电的逆变系统,具有广泛的市场前景。 Abstract:  To solve the problem of DC-AC inverter, and to utilize solar energy more efficiently, the design of maximum power point tracking inverter based on IR2101 was achieved with a high-performance, which can make the system output power maximum. SPMC75F2413A was adopted as main controller. IR2101 is a high voltage, high speed power MOSFET and IGBT driver. It adopted highly integrated voltage level transforming technology, and an external bootstrap capacitor was used, which could drive MOS tube efficiently and stably. Many functions are achieved in the system, such as DC/AC conversion, maximun power point tracking, etc. The actual test result shows that the inverter system has characteristics of strong tracking ability, high stability and reacting quickly. The design can not only be used in ordinary power inverter system, but also be used in photovoltaic power inverter system. The design has certain marketing prospects

    Foreword The four case studies that follow each have a number of common features. They each illustrate the birth of an idea and show how that idea can be realised into a marketable product. Each case study deals with engineering design and development issues and each highlights the importance of developing sound marketing strategies including market research. The importance of appropriate support mechanisms for young entrepreneurs is also covered. The case studies illustrate how successful entrepreneurs deploy a range of entrepreneurial skills and know-how. Above all, the entrepreneurs are seen to have the capacity to innovate and exercise vision. We are grateful to Liz Read, Development Manager for Enterprise and Entrepreneurship (Students) at Coventry University for providing these case studies.

  • Mobile+Satellite+Communication+Networks

    The last decade proved to be hugely successful for the mobile communications industry, characterised by continued and rapid growth in demand, spurred on by new technological advances and innovative marketing techniques. Of course, when we refer to mobile commu- nications, we tend to implicitly refer to cellular systems, such as GSM. The plight of the mobile-satellite industry over the last decade, although eventful, has, at times, been more akin to an out of control roller coaster ride.

  • The Complete Wireless Communications

    When thinking about mobile radio engineers there is a tendency to assume that the engineering function relates solely to the technical aspects of the network, such as the equipment design or the network design. That is certainly a key part of the role of a mobile radio engineer. However,increasinglyengineersarerequiredtointeractwithprofession- als from other divisions. The “complete wireless professional” should know about mobile networks; fixed networks; other types of mobile systems; regulatory and government policy; the requirements of the users; and financial, legal, and marketing issues.
