Transformerless Switch Mode Clean Power Supply Requirements + Value Proposition
Requirements
- AC grid power, 120 or 240
- Arduino brain
- Rectifier -> chopper -> capacitor smoothing -> output
- Load-limited power supply
- Fuse or current protection at output.
- Low current only up to wall current. This allows for a simple design.
Value Proposition
- Low cost, scalable, modular, simple design
- No transformer - solid state for efficiency.
- Transformers are bulky and not required. Just observe the modern new inverter welders.
