摘要：研制了一種鎘鎳航空蓄電池充電器,闡述了該系統(tǒng)的設(shè)計(jì)方案，該充電器可精確實(shí)現(xiàn)恒流充電和涓流充電功能,最后給出了實(shí)驗(yàn)結(jié)果，實(shí)驗(yàn)表明了該充電器具有輸出與電網(wǎng)高頻電氣隔離、結(jié)構(gòu)簡單、體積小、重量輕等優(yōu)點(diǎn)。 敘詞：蓄電池 充電器 恒流 Abstract：A charger for cadmium-nickel aircraft batteries is introduced. The circuit scheme and control principle are introduced in detail in this paper, which can implement the function of constant current charge and small current change.　Experimental data and waveform are given at last. Experimental results of the charger show that the charger has the advantages of electric separation, bi-directional current flow and simple frame. Keyword：batteries charger constant current
