其中信號處理電路主要完成採集輸出電流和中間直流環節電壓信號，並對採集到的電流信號進行極性變換處理的功能；驅動電路接收dsp輸出的高頻驅動信號，通過耦合器件直接驅動ipm模塊；保護電路利用採集到電氣信號對整個系統實施保護，包括過電流、過電壓、欠電壓、 ipm模塊過熱等。Then i finish the analysis from three aspects, instruction of circuit, stress of surrounding, and tolerance, thus providing basis of design. the following designs are in progress from four aspects, which are circuit design, thermal design, derating using and screening. at last, i make the update generator in batch process, and collect and analyze reliability dates again
首先進行了與可靠性相關的數據收集與分析，對故障模式進行統計；然後從電路結構、環境應力及容差三個方面進行可靠性分析，從而為關鍵的可靠性設計提供了依據；接下來的可靠性設計，從電路設計、熱設計、降額使用、篩選四個方面逐一解決了可靠性分析階段發現的問題；最後，我將改良的發生器批量生產，並從中重新收集了可靠性數據進行計算，事實證明改良后高頻無極燈的平均壽命已達到6萬小時。Environmental friendly and energy saving deaerators can be widely used in small to medium size industrial boilers, home heating boilers, beverages ( beer or juice ) manufacture and integrated circuit production, etc
環保節能除氧器在中小型工業鍋爐、民用供熱鍋爐、啤酒、飲料、集成電路製造等領域可以有廣泛的應用。Thermal and welding residual stress often produces in the proceeding of the electronic package, the residual stress release and thermal deformations of the microelectronics will reduce the assemble intensity between the chip and package, and then debase the electrical performance of the assemble circuit, numerous thermal cycling will lead to thermal fatigue or thermal failure of the microelectronics
電子封裝器件在生產的工藝過程中，往往會產生熱殘余應力以及焊接殘余應力，殘余應力的釋放作用及器件在使用過程中的熱變形，會降低集成電路晶元與封裝體的結合強度，進而降低集成電路的電性能，反復的熱循環，將導致器件的熱疲勞失效，嚴重時可導致矽片或陶瓷片破裂，使整個器件遭到破壞。Based on the application of solar heating systems in europe, presents the schemes and characteristics of typical large - scale solar heating systems and the design methods of critical elements including collectors, solar loops and heat storage devices
摘要結合歐洲太陽能供熱系統的應用情況，介紹了常見大型太陽能供熱系統的方案和特點，以及集熱器、集熱環路、蓄熱裝置等關鍵部件的設計方法。The direct - inserted solar energy water heater can be used independently for household life, and connected in series or in parallel into a collective hot water supply system for unit such as factory, mine, school, armed forces, guest house, hotel etc. where volume of hot water is needed not so much. both the full glass vacuum heat collection tube which takes natural convection of heat exchange and the heat pipe with superconducting medium have passed the ice and snow test in cold area, and have been recognized by customers in various kinds of climate conditions
這種系統包括熱管真空管全玻璃真空管，熱保溫水箱，循環網路系統，循環泵和控制器系統，其工作原理：建立於定點溫度的基礎上，介於集熱器和熱保溫水箱間的循環泵系統強制循環，集熱管吸收的太陽能不斷的轉化為熱能，使水箱里的水不斷加熱。分享友人
