This approach might be followed for circuits which did not draw much current, and/or which needed a voltage close to that of mains. But without a transformer, it will otherwise be too inefficient. (Although PWM is often used in switch mode power supplies - but still with a transformer, just using high frequencies). Transformers add a level of safety since they isolate the supply from the mains. | |
