电力系统中要求电压稳定度和无功功率满足一定的技术指标，利用带独立直流电源的级 联式多电平逆变器和多电平逆变器最优化谐波台阶式调制技术(OHSW)设计的STATCOM装置， 可以使电力系统中的电压得到稳定以及无功功率和谐波得到有效补偿。本文主要介绍了STAT- COM装置主电路的设计，主电路是STATCOM装置与系统进行交换有功功率与无功功率的环节。 该装置具有输出谐波含量低、损耗小、性能可靠等优点。(Requirements of power system voltage stability and reactive power to meet certain technical specifications, the use of DC power supply with independent level Joint multi-level inverter and multi-level inverter optimized harmonic stepped modulation (OHSW) design of the STATCOM device, Can make the power system voltage stability and reactive power to be harmonic and effective compensation. This paper describes the STAT- COM device main circuit design, is the STATCOM main circuit switching devices and systems for active and reactive power component. The device has a low output harmonic content, low loss, performance, and reliable.)

步进电机是将电脉冲信号转变为角位移或线位移的开环控制电机，是现代数字程序控制系统中的主要执行元件，应用极为广泛。。在非超载的情况下，电机的转速、停止的位置只取决于脉冲信号的频率和脉冲数，而不受负载变化的影响，当步进驱动器接收到一个脉冲信号，它就驱动步进电机按设定的方向转动一个固定的角度，称为“步距角”，它的旋转是以固定的角度一步一步运行的。可以通过控制脉冲个数来控制角位移量，从而达到准确定位的目的；同时可以通过控制脉冲频率来控制电机转动的速度和加速度，从而达到调速的目的。(Stepper motor is an open loop control motor which transforms electrical pulse signal into angular displacement or linear displacement. It is the main executive element in modern digital control system, and is widely applied. In the case of non overloaded, the motor speed and stop position depends only on the pulse frequency and pulse number, regardless of load changes, when the stepper driver receives a pulse signal, it drives stepper motor to set the direction of rotation of a fixed angle, called "step", it is the rotation of the fixed point of the operation step by step. We can control the angular displacement by controlling the number of pulses, so as to achieve the goal of accurate positioning. At the same time, we can control the speed and acceleration of motor rotation by controlling the pulse frequency, so as to achieve the purpose of speed regulation.)

DS18B20温度传感器的51汇编程序，器件资料文档用搜索找，没上传。其中当然少不了PROTEUS的仿真，KEIL+PROTEUS联合实现。而且实现了多个器件级连的功能，程序当然可以继续优化的(51 assembler DS18B20 temperature sensor, the device information document with a search to find, no upload. Which of course PROTEUS simulation, KEIL+PROTEUS jointly. And multiple devices cascaded function, the program can of course continue to optimize)
