此板大小為130*65mm,末級4塊TLP250隔離輸出,正弦波頻率可調(diào),三角波頻率可調(diào),輸出電壓可調(diào),用來驅(qū)動0-5kW正弦波逆變器.

兄弟,這個不錯,請問是用什么芯片控制的啊

可買否,????????????????????

都是很容易買的數(shù)字和模擬芯片.

調(diào)試中,還未量產(chǎn).以后將把各關(guān)鍵點的波形貼出來.

不錯啊,有沒價格?

好東西不錯來頂頂

不錯啊!有沒有商品化銷售!

是不錯.看來現(xiàn)在好多公司在搞純正弦波呀.

太簡單了,數(shù)字電路可以實現(xiàn)．有需要的和我聯(lián)系QQ:117365738

你好!有人投資并代理消售,首批200塊在外發(fā)生產(chǎn)中.

正弦波逆變有方波逆變無法比擬的性能.本人是業(yè)余制做,不代表公司.

有做過多大功率的機子?效率如何?

效率要大于0.9,最大功率是TLP250能驅(qū)動多大就多大,目前試機是1K.
