GPC 系列直流電源供應器是一部攜帶式可調整的多功能儀器，特別設計應用在電源操作的放大器，邏輯線路，正負電壓誤差非常小的精密儀器系統的追蹤上，或需要用到三組獨立電源的單體線路上，可稱得上是一部非常實用又方便的儀器。GPC 系列主要由兩組相同、獨立、可調整的直流電源供應器組成，從前面板的 TRACKING 選擇開關可選擇三種模式：獨立輸出、串聯輸出和并聯輸出。在獨立模式(INDEP)狀態時，二組主控(MASTER)、副控(SLAVE)輸出電壓、電流為獨立分離輸出，而其輸出端子到機殼或主控(MASTER)輸出端子到副控(SLAVE)輸出端子的隔離度(Isolated)有 300V。當在追蹤模式(TRACKING)狀態時，主控輸出端與副控輸出端會自動的連接成串聯模式(SERIES)或并聯模式(PARALLEL)，不需另外從輸出端接任何導線；在串聯模式時，調整主控輸出電壓(+)即有等量的副控電壓(-)輸出；并聯模式時，調整主控輸出電流，則主控輸出端即有二倍的電流量輸出。

Agilent 34401A Service Guide.pdfIEC Measurement Category II includes electrical devices connected to mains at an outlet on a branch circuit. Such devices include most small appliances, test equipment, and other devices that plug into a branch outlet or socket. The 34401A may be used to make measurements with the HI and LO inputs connected to mains in such devices, or to the branch outlet itself (up to 300 VAC). However, the 34401A may not be used with its HI and LO inputs connected to mains in permanently installed electrical devices such as the main circuit-breaker panel, sub-panel disconnect boxes, or permanently wired motors. Such devices and circuits are subject to overvoltages that may exceed the protection limits of the 34401A. Note: Voltages above 300 VAC may be measured only in circuits that are Isolated from mains. However, transient overvoltages are also present on circuits that are Isolated from mains. The Agilent 34401A are designed to safely withstand occasional transient overvoltages up to 2500 Vpk. Do not use this equipment to measure circuits where transient overvoltages could exceed this level. Additional Notices Waste Electrical and Electronic Equipment (WEEE) Directive 2002/96/EC This product complies with the WEEE Directive (2002/96/EC) marking requirement. The affixed product label (see below) indicates that you must not discard this electrical/electronic product in domestic household waste. Product Category: With reference to the equipment types in the WEEE directive Annex 1, this product is classified as a "Monitoring and Control instrumentation" product. Do not dispose in domestic household waste. To return unwanted products, contact your local Agilent office, or see www.agilent.com/environment/product for more information. Agilent 34138A Test Lead Set The Agilent 34401A is compatible with the Agilent 34138A Test Lead Set described below.

由于高重復頻率固體開關在加速器、雷達發射機、高功率微波和污染控制等領域存在的潛在優勢，美國、英國、日本和韓國等都對固體開關技術進行了大量研究，從而成為近年脈沖功率界研究的重點1。從固體元件電路結構上，固體開關可以分成兩種類型：串聯結構和累加器結構。采用串聯結構的固體開關生產廠家中，比較著名的有LLNL（Lawrence Livermore National Laboratory）和DTI（Diverfisied Technology Inc.），采用累加器結構的廠家中，比較著名的是LLNIL.和美國的First Point Scientific Ine.B32A我們已經研制成功了采用光纖控制的10kV絕緣柵雙極型晶體管（Isolated Gate Bipolar Transistor，IGBT）固體開關，盡管在該固體開關中采用的光纖收發器比較便宜，但光纖控制部分還是比較昂貴的。在一定的應用環境，如脈沖寬度為幾微秒到十幾微秒，可以采用脈沖變壓器來控制IGBT。從文獻[1]表明：只要脈沖同步和緩沖電路設計適當，即可確保固體開關中不會出現過壓。盡管脈沖變壓器隔離控制在同步精度和驅動波形一致性方面不如光纖控制，但還是可以用來控制IGBT固體開關。采用脈沖變壓器控制IGBT的主要優點是價格便宜，但其存在的主要問題是輸出脈沖寬度范圍比較有限和絕緣性能如何保證的問題。在脈沖變壓器控制的IGBT固體開關中，脈沖變壓器設計非常重要，因此下面只討論脈沖變壓器的絕緣問題和IGBT固體開關的實驗結果。
