各位老師:
你們好.
我是首次來到這里,我想在這里我一定能結(jié)識到更多的朋友.希望各位多多指教.
請問能否把12V 10A 的單端反激式的AC/DC開源電源直接并聯(lián)起來使用(三臺以上)?請給高手們給我指點(diǎn)指點(diǎn).謝謝!
關(guān)于開關(guān)電源并聯(lián)的問題.

看看UC3907資料,適當(dāng)控制就可以并了1090944320.pdf

我試過.1先并聯(lián)加輕載,分別調(diào)兩輸出電壓的微調(diào)電位器,使之電流相等;2加大負(fù)載,再調(diào)一次.這種情形適合于自己調(diào)試使用,有了麻煩自己兜著.---固定設(shè)備配套,何必如此麻煩?
多謝老師指點(diǎn),由于我這是收人家的爛攤子,原想在他原有電路及現(xiàn)有機(jī)箱結(jié)構(gòu)上進(jìn)行稍加改動.可是通過調(diào)查發(fā)現(xiàn)產(chǎn)品使用的國家電網(wǎng)條件非常低劣,而且要求可靠性極高,所以我不得不改變方案了.

跟我的想法一樣,按道理說是沒多大問題的,為了避免重新設(shè)計的麻煩,我正在對電路參數(shù)進(jìn)行調(diào)整,并機(jī)后做好各種極限試驗再出貨,這樣心里踏實(shí)些.我非常感激老師這樣熱心給我提供這些寶貴的意見,請別閑少給20分一點(diǎn)心意.
simple and effective method for direct current sharing:
1. Increase inner resistance of power supply, the mean that to make worse load regulation.
2. Adjust the regulation to enter in +/-1% range under full load condition,maybe can less,
after assemmbly,B/I and tapping process, then double check the regulation to make sure which can meet the +/-1% regulation under full load, if fail, then re-adjust the reglation and re-flow the full process.
