Transformerless Power supply 220v ac-20v

[powering led with 220 v AC] Have you wondered how Bulbs/lights work directly on mains 220v AC input without a stepdown transformer to lower voltage? The circuit discussed in this article shows and explains how to power LEDs from 220v ac source without using a stepdown transformer. The same concept is used in our modern […]
