Description: 开关电源是一种电压转换电路，主要的工作内容是升压和降压，广泛应用于现代电子产品。因为开关三极管总是工作在 “开” 和“关” 的状态，所以叫开关电源。开关电源实质就是一个振荡电路，这种转换电能的方式，不仅应用在电源电路，在其它的电路应用也很普遍，如液晶显示器的背光电路、日光灯等。开关电源与变压器相比具有效率高、稳性好、体积小等优点，缺点是功率相对较小，而且会对电路产生高频干扰,变压器反馈式振荡电路，能产生有规律的脉冲电流或电压的电路叫振荡电路，变压器反馈式振荡电路就是能满足这种条件的电路

Description: 1、制作霓虹灯闪光花样控制器：
常用的两种类型高压霓虹灯闪光花样控制器常因凸轮磨损、铜板磨损或电机损坏而不能正常工作，还因其为低速电机机械传动不能调速，限制了它的灵活性。图中所示的霓虹灯发光花样控制电路具有寿命长，逻辑功能多，成本低（只有机械控制的40 ），结构简单等优点。
此电路能控制1、2、3、4个字霓虹灯依次点亮，即“图案展开”；4、3两个字依次熄灭，即“图案收回”；在第一个字亮的基础上，第1、2、3、4个字依次独立点亮一次，然后从头循环。
2、电路原理：
IC5为时基集成电路组成脉冲振荡器，为IC1十进制计数/分配器提供时钟脉冲。IC1 10个输出Q0~Q9组成双四路输出电路，用来控制IC3、IC4四二端“与”门电路不同输入与门组合，使4路霓虹灯按次序闪亮发光。此电路所控制的4路霓虹灯发光状态中，至少有一字亮，避免了一片漆黑的不良后果。另外可根据需要，讲上述4路控制扩展成5路、6路或更多路。图中用灯（P1、P2、P3、P4）代表高压霓虹灯变压器。
-A production of neon flash pattern controller:
The commonly used two types of high-pressure neon flash pattern controller due to cam wear, copper, wear or motor damage, but not working properly, but also because of its low-speed motor mechanical transmission can not be governor, limiting its flexibility. The neon light-emitting pattern control circuit shown has the advantage of long life, the logic function, low cost (only 40 of the mechanical control), and a simple structure.
This circuit can control 1, 2, 3, 4 words to the neon lights were lit, and that "the pattern expand 4,3 word turn off, ie," the pattern of recovery " in the first word of the brightest on the basis of a , 2,3,4 a word followed by independent light, and then scratch cycle.

Description: 该模型是对50kW、380V、50Hz三相三电平逆变器的两个相同电路进行建模。IGBT逆变器采用SPWM技术，(8kHz载频)将直流电源从a +/-200Vdc源转换为220V AC, 50Hz。逆变器通过75kVA 220/380V变压器输入50kW电阻负载。变频器输出采用L-C滤波器滤除主要产生于8kHz开关频率倍数(Fh=n*8000 +/-k*50Hz)附近的谐波频率Fh。逆变器所需的12个逆变脉冲由PWM发生器块产生。该系统以恒定的调制指标在开环中工作。
电路1使用三电平桥块对逆变器进行建模。电路2使用独立的IGBTs和二极管块。用开/关延时块模拟死区，仅在电路1上应用。(It is easy for us)
