It shows that the design works properly . then an 8 bit mcu picoblaze developed by xilinx company is used for the further sopc design of remote controller . the circuit structure and realization are discussed and most components are debugged successfully 在此基础上,做出了用xilinx公司的可编程spartan系列芯片和该公司所提供的8位mcu软核( ipcore )实现sopc的方案做出了初步设计,各程序模块分别通过调试。
The single - stage isolated inverters can fulfill all the functions of two - stage inverters in one stage , including dc / ac inverter , voltage adjustment and electrical isolation . thus , the circuit structure and the control schemes can be simplified , with resultant high reliability and reduced cost 单级式隔离逆变技术只需一级功率变换就可完成传统两级逆变电路的全部功能包括dc / ac逆变、电压调整及电气隔离。
Researches on apf are focused on main circuit structure forms ( series - type , shunt - type , series - and shunt - type ) , harmonic current detecting approaches and control strategies to compensate current etc . this paper mainly deals with harmonic current detecting approaches 有关有源电力滤波器的研究主要集中在主电路结构形式(串联、并联和串并联) 、谐波电流检测方法和补偿电流的控制方法等方面。本论文重点研究了谐波电流的检测方法。
To comply with the low - power - consumption application , low - voltage design is taken into account by using some special circuit structures . . besides there are many nonideal effects in pll which degrade the loop performance badly , some efficient solutions have been put forward to suppress the undesired ones 此外论文还讨论了若干制约环路性能的非理想效应,并在借鉴国外相关理论成果的基础上,成功设计了克服这类效应的一些改进电路。
Then according to the request of algorithm and characteristic of fpga , the module was divided and the circuit structure was designed , this module includes these functions as follows : initialing population 、 calculating fitness 、 reproduction 、 corssover 、 mutation and population storing 然后依据算法要求以及现场可编辑门阵列( fpga )的特点进行模块划分与电路结构设计,具体包括初始化群体、适应度计算、选择、交叉、变异、群体存储等功能模块。
