Inversion layer is formed when Vge>Vth2. Apply positive collector bias, +Vce3. Electrons flow from N+ emitter to N-drift layer providing the base current for the PNP transistor4. Since J1 is forward blased, hole carriers are injected from the collector (acts as an emitter).5. Injected hole carriers exceed the doping level of N-drift region (conductivity modulation).

  • 電子元器件系列知識(shí)—IGBT

    一、IGBT 驅(qū)動(dòng)1 驅(qū)動(dòng)電壓的選擇IGBT 模塊GE 間驅(qū)動(dòng)電壓可由不同地驅(qū)動(dòng)電路產(chǎn)生。典型的驅(qū)動(dòng)電路如圖1 所示。圖1 IGBT 驅(qū)動(dòng)電路示意圖Q1,Q2 為驅(qū)動(dòng)功率推挽放大,通過光耦隔離后的信號(hào)需通過Q1,Q2 推挽放大。選擇Q1,Q2 其耐壓需大于50V 。選擇驅(qū)動(dòng)電路時(shí),需考慮幾個(gè)因素。由于IGBT 輸入電容較MOSFET 大,因此IGBT 關(guān)斷時(shí),最好加一個(gè)負(fù)偏電壓,且負(fù)偏電壓比MOSFET 大, IGBT 負(fù)偏電壓最好在-5V~-10V 之內(nèi);開通時(shí),驅(qū)動(dòng)電壓最佳值為15V 10% ,15V 的驅(qū)動(dòng)電壓足夠使IGBT 處于充分飽和,這時(shí)通態(tài)壓降也比較低,同時(shí)又能有效地限制短路電流值和因此產(chǎn)生的應(yīng)力。若驅(qū)動(dòng)電壓低于12V ,則IGBT 通態(tài)損耗較大, IGBT 處于欠壓驅(qū)動(dòng)狀態(tài);若 VGE >20V ,則難以實(shí)現(xiàn)電流的過流、短路保護(hù),影響 IGBT 可靠工作。2 柵極驅(qū)動(dòng)功率的計(jì)算由于IGBT 是電壓驅(qū)動(dòng)型器件,需要的驅(qū)動(dòng)功率值比較小,一般情況下可以不考慮驅(qū)動(dòng)功率問題。但對(duì)于大功率IGBT ,或要求并聯(lián)運(yùn)行的IGBT 則需要考慮驅(qū)動(dòng)功率。IGBT 柵極驅(qū)動(dòng)功率受到驅(qū)動(dòng)電壓即開通VGE( ON )和關(guān)斷 VGE( off ) 電壓,柵極總電荷 QG 和開關(guān) f 的影響。柵極驅(qū)動(dòng)電源的平均功率 PAV 計(jì)算公式為:PAV =(VGE(ON ) +VGE( off ) )* QG *f對(duì)一般情況 VGE( ON ) =15V,VGE( off ) =10V,則 PAV 簡(jiǎn)化為: PAV =25* QG *f。f 為 IGBT 開關(guān)頻率。柵極峰值電流 I GP 為:

  • 三極管開關(guān)電路設(shè)計(jì)的詳細(xì)過程

    三極管除了可以當(dāng)做交流信號(hào)放大器之外, 也可以做為開關(guān)之用。嚴(yán)格說起來, 三極管與一般的機(jī)械接點(diǎn)式開關(guān)在動(dòng)作上并不完全相同, 但是它卻具有一些機(jī)械式開關(guān)所沒有的特點(diǎn)。圖1所示,即為三極管電子開關(guān)的基本電路圖。由下圖可知,負(fù)載電阻被直接跨接于三極管的集電極與電源之間,而位居三極管主電流的回路上。輸入電壓Vin 則控制三極管開關(guān)的開啟(open) 與閉合(closed) 動(dòng)作,當(dāng)三極管呈開啟狀態(tài)時(shí), 負(fù)載電流便被阻斷, 反之, 當(dāng)三極管呈閉合狀態(tài)時(shí), 電流便可以流通。詳細(xì)的說,當(dāng)Vin 為低電壓時(shí),由于基極沒有電流,因此集電極亦無電流,致使連接于集電極端的負(fù)載亦沒有電流,而相當(dāng)于開關(guān)的開啟,此時(shí)三極管乃勝作于截止(cut off) 區(qū)。

    VME has been the de-facto bus standard for Commercial off the Shelf(COTS ) Circuit Card Assemblies since the 1980's. VME boards have proven to be remarkably capable of evolving to support newer technologies with innovations such as VME Subsystem Bus, PCI Mezzanine Cards(PMC's) and VME320.However, advances in technologies, appearing particularly in interconnects, have demonstratedthe need for an advance in system development. This advance needs to accommodate high speed interconnect, particularly serial interconnects, and higher power delivery in concert with better heat removal.
