Description: This DIY 12V to 220V voltage converter is built with a CMOS 4047, which serves as the main component of this compact voltage converter that transforms 12V DC into 220V AC. The 4047 functions as an astable multivibrator; at pins 10 and 11, it produces a symmetrical rectangular signal that is amplified by two Darlington transistors before reaching the secondary coil of a transformer (2x10V / 60VA). With the assistance of P1, the output frequency can be adjusted between 50Hz and 400Hz. Although this device is not part of any professional DC to AC converters, it can be effectively used for some home appliances.
This circuit design utilizes the CMOS 4047 integrated circuit, which is known for its versatility in generating square wave signals. In this application, the 4047 operates in astable mode, generating a continuous square wave output that can be modulated for frequency variation. The output frequency can be adjusted using a potentiometer (P1), allowing for customization based on the specific requirements of the load.
The generated square wave signal from the 4047 is fed into two Darlington transistor pairs, which serve to amplify the current. These transistors provide the necessary gain to drive the transformer effectively. The transformer is designed to step up the voltage from 12V to 220V, allowing for the operation of standard AC appliances.
The transformer used in this design is rated at 2x10V with a power capacity of 60VA. This rating indicates that the transformer can handle a maximum load of 60 watts, making it suitable for small household devices. The choice of a transformer with a dual primary winding configuration (2x10V) allows for better efficiency and output stability.
It is important to note that while this DIY voltage converter can effectively power certain home appliances, it may not meet the stringent requirements of professional-grade DC to AC converters. Users should take care to ensure that the connected appliances do not exceed the power rating of the transformer to prevent damage to the circuit. Additionally, safety precautions should be observed when working with high voltages to avoid electric shock or fire hazards.This DIY 12V to 220V voltage converter is build with CMOS 4047 that is the main component of this small voltage converter that transforms a 12V DC into 220V AC. 4047 is used as a astable mutivibrator, at pins 10 and 11 will have a symmetrical rectangular signal wich is amplified b 2 Darlington transistors and finally reach the secondary coil of ma
