In addition , each rectifier arm was made of many thyristors that are parallel connection , so there had the problem that current was distributed equably , in the same way , current - sharing coefficient was a vary important technology index 另外，每一个整流臂由多只晶闸管并联而成，这样就存在电流均匀分配的问题，均流系数同样是一个非常重要的技术指标。
The problems such as the circuit and the working mode of the pwm dc / dc modules , the configuration of the parallel connection , the usage of the input dc bus , and the system control strategy were analyzed and discussed as well 论文对pwmdc dc电源的电路结构和工作模式、并联系统的结构、是否采用直流输入母线、以及系统的控制方案等问题进行了分析和讨论。
The said energy storing water tank consists of warm water storage tank of multiple stage heating and hot water storage tank , in parallel connection with multi - stage confluent water - heating tank 所述的储能水箱是一个以上的水箱，储能水箱包括分级加热式温水储热水箱及终温储热水箱，分级加热式汇流热水箱与分级加热式温水储热水箱及终温储热水箱间的连接是并联连接。
Sudden loading and sudden unloading , parallel connection , etc . ) . this soft can easily set parameters of the system and the components , and it also can set many sorts of faults . it can display the results statically or dynamically 该程序可任意设置系统的、元件的参数；可以设置各种故障；能够静态、动态实时的显示仿真结果。 3 、运用神经网络的方法，进行暂态稳定分析。
Heating principle of intermediate frequency induction furnace and some factors affecting its power factor are discussed , some betterments that parallel connection spacer circuit is replaced by interfusion connection spacer circuit are put in practice 摘要对中频感应炉的加热原理以及其功率因数的影响因数进行了探讨，并将不能恒功率输出的并联逆变电路改进为混联逆变电路。
We introduce the category , property of the reactive power source and the component of the power market , including the generator , phase modifier , condenser , svc , and parallel connection reactor , and discuss the reactive power balance in power market 介绍了无功市场中无功电源：发电机、调相机、电容器、静止补偿器、并联电抗器以及他们的特点；讨论了无功市场中各组成部分以及无功市场的平衡。
When installing parallel connection heating cables , pay attention to the position of two " cold ends " to ensure the heaters to be put at the positions needed to be heated . and core wires , heating threads and shiedlding layers can not touch each other in case of short circuit 安装并联带时，应注意二头“冷端”位置，确保带头发热段控制在需伴热的部位：并注意芯线、发热丝与屏蔽层相互之间不能触碰，以免短路。
In the third chapter , it has analyzed the rating expansion of induction heating power supply . the series and parallel connections of power electronic devices are discussed here . the inverter and machine series and parallel connections are discussed 第三章分析了感应加热电源的扩容技术，分析了器件的串并联扩容时需要注意的问题，分析了逆变器以及整机串并联的扩容技术中常用拓扑结构和各自存在的问题。
This kind of switch use the unilateral fin - line as the basic transmission line , the beam lead pin diode of alpha co . ltd is the control element , there is two diodes in each channel and they are welded in circuit in parallel connection 本课题主要研究的是毫米波鳍线pin管单刀双掷开关。该开关采用单侧鳍线作为基本传输线，控制器件选用alpha公司的梁式引线pin二极管，每路使用两只，采用并联形式焊接在电路中。
At the same time the system can check the cutting or parallel connection of telephone line . when danger the user can also give an alarm quickly through the keyboard or through the remote controller . at present , the product has been put into market 另外，该系统可实现电话并机和掉线的检测，紧急状态下也可由主机或遥控按键实现直接报警，是一种适合于家庭、办公室和仓库等处的可靠性较好的安全防范装置。
