This is the DC / AC Voltage Inverter 12v for 110 - 220V Simple and Powerful. Here is from a voltage inverter 12 Volts DC to 110 or 220 Volts AC. It is capable of generating a 50 or 60 Hz AC voltage (AC) with a square wave, which can feed most electronic equipment in a home.
Equipment with some types of motors will not work well with this voltage inverter and may even be damaged, so use it only on equipment that does not require AC power or that is not as sensitive to the type of wave.
Voltage Inverter
This circuit is very simple, uses less than 12 component to build a DC to AC voltage inverter.
DC / AC Voltage Inverter 12v for 110 - 220V Circuit Diagram
The principle of this circuit is to generate a frequency between 50 and 60Hz through the integrated circuit CD 4074, this signal coming from pins 10 and 11, which are in opposite phases of 180º, these 50 Hertz pulses are taken to the IRFZ MOSFET transistors 44 that amplify these pulses giving them more current, after amplifying the pulse it is taken to the transformer generating high voltage in the secondary of 220Volts or 110 Volts AC depending on the used transformer.
The output waveform of the inverter is square and is improved almost to a "modified" wave with a Cn filter of 220nF, in my opinion the output is a square wave cropped, well away from being a sine wave.
The integrated circuit used. the CD4047 is a TTL integrated circuit that operates both in monostable mode and in steady mode. Below the CD4047 pinout.
The oscillator components of the CD4047, R1 / C1, are a capacitor (between pins 1 and 3) and a resistor (between pins 2 and 3), they will determine the output pulse width in monostable mode, and the output frequency in astable mode.
To increase the output current (power) a high current battery, more MOSFETS transistors in parallel and a compatible transformer should be used. For example, to obtain 240W output the battery used is at least 20A.
