一、IGBT 驱动1 驱动电压的选择IGBT 模块GE 间驱动电压可由不同地驱动电路产生。典型的驱动电路如图1 所示。图1 IGBT 驱动电路示意图Q1,Q2 为驱动功率推挽放大,通过光耦隔离后的信号需通过Q1,Q2 推挽放大。选择Q1,Q2 其耐压需大于50V 。选择驱动电路时,需考虑几个因素。由于IGBT 输入电容较MOSFET 大,因此IGBT 关断时,最好加一个负偏电压,且负偏电压比MOSFET 大, IGBT 负偏电压最好在-5V~-10V 之内;开通时,驱动电压最佳值为15V 10% ,15V 的驱动电压足够使IGBT 处于充分饱和,这时通态压降也比较低,同时又能有效地限制短路电流值和因此产生的应力。若驱动电压低于12V ,则IGBT 通态损耗较大, IGBT 处于欠压驱动状态;若 VGE >20V ,则难以实现电流的过流、短路保护,影响 IGBT 可靠工作。2 栅极驱动功率的计算由于IGBT 是电压驱动型器件,需要的驱动功率值比较小,一般情况下可以不考虑驱动功率问题。但对于大功率IGBT ,或要求并联运行的IGBT 则需要考虑驱动功率。IGBT 栅极驱动功率受到驱动电压即开通VGE( ON )和关断 VGE( off ) 电压,栅极总电荷 QG 和开关 f 的影响。栅极驱动电源的平均功率 PAV 计算公式为:PAV =(VGE(ON ) +VGE( off ) )* QG *f对一般情况 VGE( ON ) =15V,VGE( off ) =10V,则 PAV 简化为: PAV =25* QG *f。f 为 IGBT 开关频率。栅极峰值电流 I GP 为:

f your application uses MFC in a shared DLL, and your application is in a language other than the operating system s current language, you will need to copy the corresponding localized resources MFC42XXX.DLL from the Microsoft Visual C++ CD-ROM onto the system or system32 directory, and rename it to be MFCLOC.DLL. ("XXX" stands for the language abbreviation. For example, MFC42DEU.DLL contains resources translated to German.) If you don t do this, some of the UI elements of your application will remain in the language of the operating system.

The cart with an inverted pendulum, shown below, is "bumped" with an impulse force, F. Determine the dynamic equations of motion for the system, and lin earize about the pendulum s angle, theta = Pi (in other words, assume that p endulum does not move more than a few degrees away from the vertical, chosen to be at an angle of Pi). Find a controller to satisfy all of the design re quirements given below.
