300W逆變器,300W Power Inverter

關(guān)鍵字：逆變電路及圖

Here is a schematic 300W power inverter with 12 volt batteries as a source. This inverter is controlled by 555 timer and CD4017 decade counter. You should try to build this inverter, because it can be used to power load 300W. With the power was sufficient to illuminate a few light bulbs at night for your camping needs.

This 300W power inverter is quite simple but powerful, efficient, and stable. The inverter is built using a 10V center tap transformer. A 555 Timer IC and a 4017 decade counter IC used to produce a modified sine wave of 50 Hz.

300W Power Inverter Circuit

Timer 555 will produce a frequency of 200 Hz (see the schematic for more info) by adjusting the potentiometer value of 500K. CD4017 produces the pulse trains on pin 2 and pin 7 of  CD4017 is connected to the gates of the MOSFET STP36NF06L. It then directed to the transformer primary side. There will be 220V AC at the transformer secondary side of the 300W power inverter.

In order for the inverter system can run to efficiently use the cooling fan, even though the heatsink is still needed. Be careful you are working with AC power at the output of the 300W power inverter.

這里是一個(gè)300W功率逆變器的電路圖，12伏電池作為一個(gè)電源。該變頻器由555定時(shí)器和CD4017十進(jìn)制計(jì)數(shù)器控制。你可以嘗試建立這個(gè)逆變器，因?yàn)樗�可以用�?lái)為300W負(fù)載供電。在晚上為了野營(yíng)的需要，足以照亮一盞燈泡。
 
這款300W的逆變器非常簡(jiǎn)單但功能強(qiáng)大，高效穩(wěn)定。逆變器使用10V中心抽頭變壓器構(gòu)建。一個(gè)555定時(shí)器IC和一個(gè)4017十進(jìn)制計(jì)數(shù)器IC，用來(lái)產(chǎn)生一個(gè)50Hz的修正正弦波。

為了使變頻器系統(tǒng)能夠有效地使用冷卻風(fēng)扇，即使仍然需要散熱器。請(qǐng)注意，在300W功率逆變器的輸出端使用交流電源。
