300W逆变器,300W Power Inverter

关键字：逆变电路及图

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.

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.

这里是一个300W功率逆变器的电路图，12伏电池作为一个电源。该变频器由555定时器和CD4017十进制计数器控制。你可以尝试建立这个逆变器，因为它可以用来为300W负载供电。在晚上为了野营的需要，足以照亮一盏灯泡。
 
这款300W的逆变器非常简单但功能强大，高效稳定。逆变器使用10V中心抽头变压器构建。一个555定时器IC和一个4017十进制计数器IC，用来产生一个50Hz的修正正弦波。

定时器555将通过调整500K的电位器值产生200赫兹的频率（更多信息参见原理图）。 CD4017产生CD4017的引脚2和引脚7上的脉冲串连接到MOSFET STP36NF06L的栅极。然后导向变压器初级侧。 300W逆变器的变压器二次侧会有220V的交流电。
 
为了使变频器系统能够有效地使用冷却风扇，即使仍然需要散热器。请注意，在300W功率逆变器的输出端使用交流电源。
