1、48V48V鉛酸儲(chǔ)電池充電器鉛酸儲(chǔ)電池充電器摘要：摘要：本設(shè)計(jì)介紹了充電器對(duì)蓄電池充電的一般原理，從蓄電池內(nèi)部氧循環(huán)的設(shè)計(jì)理念出發(fā)，研究各種充電方法對(duì)鉛酸蓄電池壽命的影響。針對(duì)蓄電池充電過程中出現(xiàn)的種種問題，提出對(duì)鉛酸蓄電池實(shí)現(xiàn)簡(jiǎn)易脈沖充電器設(shè)計(jì)方案。將整個(gè)設(shè)計(jì)方案分解成兩個(gè)模塊電路的設(shè)計(jì)，通過分析和計(jì)算獲得每個(gè)模塊中各個(gè)元器件的參數(shù)，最后將各個(gè)模塊進(jìn)行組合獲得完整的電路。整個(gè)電路分為主電路和觸發(fā)電路，通過控制觸發(fā)電容的充電時(shí)間，以調(diào)整

2、單結(jié)晶體管的占空比，再將輸出的觸發(fā)信號(hào)調(diào)節(jié)可控硅的導(dǎo)通及關(guān)斷時(shí)間，從而調(diào)節(jié)充電電流，實(shí)現(xiàn)對(duì)蓄電池的脈沖式充電，這個(gè)方案不僅可實(shí)現(xiàn)對(duì)蓄電池快速充電，同時(shí)可以減少析氣，消除硫化，進(jìn)行均衡充電，從而大大地延長(zhǎng)了鉛酸蓄電池的使用壽命。關(guān)鍵詞：關(guān)鍵詞：充電器鉛酸蓄電池，觸發(fā)，單結(jié)晶體管，可控硅。III目錄前言......................................................................
