300W逆变器
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.

1000W逆变器电路图,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伏逆变器电路,CD4047 POWER INVERTER
CD4047 500W 12V 220伏逆变器电路
可以转换12V直流转220伏交流。4047是用来产生方波。
基本公式为P =VI输入输出之间的变压器,输入功率=输出功率
因此,变压器12V到220伏,但输入绕组必须能够承受20A。
