Circuit Design:
- TL494 Configuration:
The TL494 will be set up in a configuration to produce PWM signals that control the MOSFETs’ switching frequency and duty cycle.
- MOSFET Driver Stage:
The TL494’s output pins will drive the MOSFETs to switch the DC input from the battery into an alternating current to the transformer.
- Transformer and Rectification:
The transformer will step up the voltage to 220V AC, and the rectification circuit will convert it back to DC.
- Output Filtering:
Capacitors and inductors will smooth out the converted AC wave form to produce a stable 220V output.
