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.)

USB 1.1 Slaver for CH375:CH375做slaver的程序,单片机用89C2051.与我之前上传的CH375-HOST对应,联系起来使用. (USB 1.1 Slaver for CH375 : CH375 do slaver procedures, Microcontroller with 89 C2051. Before I uploaded CH375- HOST counterpart and linked use.)

某公司安装了电子门，要设计门禁系统： 公司的雇员可以凭借密码、胸卡或指纹进入公司 计算机根据雇员的验证方式对其身份进行验证 管理员在监控室可以通过按钮直接开启电子门 访客可以按门铃请求进入，由管理员为其放行 管理员可以为新职员设置密码 (A company to install an electronic gate, to design access control systems: the company' s employees can rely on passwords, badges or finger into the company computer, authentication of the employee to verify their identity can be an administrator in the control room directly through the button to open electronic gates that visitors can rang the doorbell of the request to enter an administrator can be released by the administrator of its staff to set a password for the new)
