Basic Circuit Design:

The CD4047BE IC generates squar waves at a specified frequency determined by connecting an external component to it . 

These square waves are then amplified and utilized to drive the Mosfets, which control the power flow and transform.

The transform steps up the volts from 12V DC to 220V AC .

Circuit Connections:

Connect pin 4 (Reset) of CD4047BE to ground, pin 5 (Control) connect with 15k resistor to on pin 14 ( VDD 12v Pin 14) .

Connect pins 10 and 11 of CD4047BE to the all gate of the IRFP450 through a resistor.

Connect the emitter pin of Tip41C to the pin 14 of the CD4047BE.

Connect the source of an IRFP450 MOSFET to ground and its drain to one end of the primary winding of the transformer.

Connect the midle of the primary winding of the transformer to +12V.

Connect the secondary winding of the transformer to the load (220V AC devices).

Component Sizing:

Choosing the outer components (resistors, capacitors) for CD4047BE determines the frequency of the output waveforms! Validate the MOSFET's capability to manage the energy needs of your alternator (4500W).

Testing and Optimization:

Testing lower power rating adjustments circuits for functionality and safety in the beginning is quite needed. Voltage and current measures at different points in the circuit are necessary to confirm its operation as planned . Improving component scope and circuit design for better performance and dependability is recommended .

 Safety Precautions:

1. For the MOSFET and other components that produce heat, make use of heatsinks that are appropriate.

2. Guarantee appropriate protection and establish a system to forestall electric shock.

3. Implementing fuses and circuit breakers to safeguard against overcurrents and short circuits is strongly recommended .

Making a definite schematic and perhaps talking with a hardware master would be prudent for a powerful task. When creating and utilizing high-power electrical devices, ensure that you adhere to safety guidelines.
