How to connect a battery in Series?
The positive terminal of the first battery is connected to the negative terminal of the second battery, the positive terminal of the second is connected to the negative of the third, etc. The voltage of the assembled battery is the sum of the battery voltages of the individual batteries. So the batteries are connected: + to - to + to - to + to -, etc. The capacity of the battery is unchanged.

How to connect a battery in Parallel?
The positive terminal of the first battery is connected to the positive terminal of the second battery, the positive terminal of the second is connected to the positive of the third, etc. and The negative terminal of the first battery is connected to the negative terminal of the second battery, the negative terminal of the second is connected to the negative of the third, etc. So the batteries are connected: + to + to + and - to - to -. In this configuration, the capacity is the sum of the capacities of the individual batteries and voltage is unchanged. For example, if you take 5 6V 10AH batteries and connect the batteries in series, you would end up with a battery array that is 30 Volts and 10AH. If you connect the batteries in parallel, you would end up with a battery array that is 6 Volts and 50AH. By the way, this is how ordinary auto batteries are made. 6 2volt cells are put in series to give 12v battery and the 6 cells are just enclosed in one case. Many ni-cad batteries are done the same way.

大功率三相UPS常用的多相多重疊加整流器有12相二重疊加、18相三重疊加和24相四重疊加三種。這三種多相多重疊加整流器,都是采用多重疊加的方式消除市電輸入電流中低次諧波的,相數(shù)越多消除的諧波越多,但電路和輸入整流變壓器的構(gòu)造也越復(fù)雜,制造成本也越大。就技術(shù)實(shí)現(xiàn)的方

法而言可以分為三種:
(1)等幅多重疊加:這是一種只用相位不同進(jìn)行多重疊加來(lái)消除諧波的。
(2)變幅多重疊加:這是一種用相位不同和幅值不同兩種方式進(jìn)行多重疊加來(lái)消除諧波的,效果比等幅多重疊加好一些。
(3)SCR變幅多重疊加:這是一種用相位不同、幅值不同和波形不同三種方式進(jìn)行多重疊加來(lái)消除諧波的,效果比等幅多重疊加和變幅多重疊加都好。

多相多重疊加整流器的參數(shù)如表1所示。從消除諧波的效果來(lái)看,SCR24相整流四重疊加整流器的消諧波能力,當(dāng)控制角α<15°時(shí),可以使市電的輸入功率因數(shù)PF=0.9971·cos15°=0.963。為了簡(jiǎn)化輸入整流變壓器的結(jié)構(gòu),在12相二重疊加整流器中加入諧波注入電路如圖1所示,

也可以達(dá)到24相四重疊加整流器的消諧波效果[2],諧波注入電路的功率只有整流器總?cè)萘康?%。其中圖1(a)為整流橋串聯(lián)的電路,圖1(b)為整流橋并聯(lián)的電路。圖1(a)的注入電路是由變壓器Tr(變比為1:k)及二極管VD1～VD4組成;圖1(b)的注入電路是用平衡電抗器的次級(jí)和二極管VD1～VD4組成。

諧波注入法的難點(diǎn)是變壓器Tr的變比需用實(shí)驗(yàn)來(lái)確定。諧波注入式整流是一種代價(jià)小、收效大的巧妙的整流方法,下面簡(jiǎn)單介紹一下它的工作原理。諧波注入的原理是:由于整流橋Ⅰ和Ⅱ是串聯(lián)或并聯(lián)的,由于輸入整流變壓器的移相作用,POWER SONIC蓄電池PS-1270 12V7AH應(yīng)急使兩個(gè)電流源的輸出電流有效值相同,但電流瞬時(shí)值波形有30°的相位差。因此電路中的電流瞬時(shí)值是不相同的,有30°的相位偏移,故注入電路在整流器的輸出端將會(huì)產(chǎn)生一個(gè)頻率為6倍的從0到Ud的直流電壓,此電壓即為諧波注入電壓。用這個(gè)電壓注入后就會(huì)使整流器的市電輸入電流成為24相四重疊加整流器的市電輸入電流波形如圖1(c)所示。這是一種代價(jià)小、收效大的巧妙方法。此法的難點(diǎn)是變壓器Tr的變比需要通過(guò)試驗(yàn)確定。
