hi Sayeed, I really enjoy the way you explain the engineering facts and watched most of your videos. I appreciate all your efforts. Please always make more interesting videos. waiting for your next videos. I am an Engineering graduate and working professional in computers. I saw your video related to data. if you know more about the data and computers internal functional with the data and how energy plays a major role over there would be welcome. Any science in the day to day life is also more interestingly watchable for me. All the best.

Instead of first converting AC to DC then using driver IC for square wave and next stepping down AC and finally converting into DC, why can't we first step down AC to the required voltage and then finally convert it to required DC input?

1. Why can't we give the input 230 AC volt directly to the step down transformer and then convert it to DC and give it to LED? Why are converting the input AC to DC and then again to AC and to transformer and then converting it to DC. Why my point 1 is not valid?

[@engineeringfacts]

1. direct transformer output produce more ripples.. 2. Transformer will react as per the primary, in the primary voltage increase, secondary also increase, you cannot control. But through MOSFET you can control transformer output. 3. Using a transformer in high voltage, will reduce the cost of components and transformer coil.
