1000W逆變器電路圖,1000W Mosfet Power Inverter

This power inverter circuit will provide a very stable “Square Wave” Output Voltage. Frequency of operation is determined by a pot and is normally set to 60 Hz. Various “off the shelf” transformers can be used. Or Custom wind your own for best results.
Additional MosFets can be paralleled for higher power. It is recommended to Have a “Fuse” in the Power Line and to always have a Load connected”, while power is being applied. The Fuse should be rated at 32 volts and should be aproximately 10 Amps per 100 watts of output. The Power leads must be heavy enough wire to handle this High Current Draw! appropriate Heat Sinks Should be used on the RFP50N06 Fets. These Fets are rated at 50 Amps and 60 Volts. Other types of Mosfets can be substituted if you wish.
There ARE Limitations! I have had numerous requests for an Inverter for 1000 watts and Even MORE. Sorry I Don’t feel this is Practical. At 1000 Watts and operating from a 12 Volt Source, the Input Current will be close to 100 AMPS. That would Require a HUGH Size of a Primary Wire

CD4047 500W 12V 220伏逆變器電路,CD4047 POWER INVERTER

 

CD4047 500W 12V 220伏逆變器電路
可以轉(zhuǎn)換12V直流轉(zhuǎn)220伏交流。4047是用來(lái)產(chǎn)生方波。
基本公式為P =VI輸入輸出之間的變壓器，輸入功率=輸出功率
因此，變壓器12V到220伏，但輸入繞組必須能夠承受20A。

小功率工頻逆變器,50Hz power inverter

 

 

這里介紹一種簡(jiǎn)單的小型逆變電源．可以在交流電源斷電的情況下，對(duì)25W、35W等小型電烙鐵或者小功率燈泡繼續(xù)供電。以應(yīng)急使用。

晶體管T1和T2(BC547)構(gòu)成方波多諧振蕩器，輸出50Hz信號(hào)。此互補(bǔ)輸出由T1、T2集電極送至由T3、T5和T4、T6構(gòu)成的PNP達(dá)林頓驅(qū)動(dòng)級(jí)．并將輸出連接至由T7、T8構(gòu)成的推挽放大級(jí)。

變壓器X1次級(jí)經(jīng)12—0—12端子連接推挽放大器T7、T8的集電極．中心抽頭接12v電池(7Ah)，初級(jí)則送出220v交流電供小功率阻性負(fù)載使用。

使用時(shí)，只需合上開(kāi)關(guān)S1，變壓器X1就會(huì)在其初級(jí)端送出220v交流電壓，需要根據(jù)負(fù)載的大小．調(diào)整電池的容量、T5～T8的散熱器大小和變壓器的大小等等。
