100v to 250v regulated LED improved

"0òu yæah" i see someone catch whats come on ... now design is good and no heat is generated means u know whats are for those all switchers and fancy techniques used in all kind of inverters and power supplies. And how important is this apect in commercial aplications together with noise reduction and removing all kind of nonlinearities introduced back to network other words a mighty Power Factor correction and EMI radiation reduction. So u need to know why ordinary diodes are bad very bad not saying about triacks. Those are cursed son of emi devil a world champ generator of noise of all kind and mighty Power factor corruptor striking both sides a linear and nonlinear. Why no one use bigger caps for power supplies instead of transformers ad switchers (and this is not due lack of proper isolation or lack of good relable caps) why a large heavy air gaped ballast chokes with high copper loses due to force of using soft magnetics where wound a one henry windding require twice more turns than for two transformer primaries of 10 henry each. And yet they still are better solution than capacitor even when they have efficciency around 70-80% compared to far more than 90% for any cap. Time for step 2

Thanks! Lol. You are right!

There are good reasons to not use transformers. One is to have boostrap power for powersupplys another is just cost reduction in consumer products. However the blind current which it generate must be low enough and the circuit behind liniear more or less. LEDs unfortunately are not linear. Switching 120Hz 3Watt blind nonlinear current is a nice radio station. You may endup with additional caps to store energy and hide after startup nonlinearity and a coil at powerline to reduce RF into powerline. This again increase the cost.... I like to see this as an little challenge to find a circuit which is cheap, overton free and secure (caps are not a calvanic speparation). Keep on inventing

A main reason against caps is price of capacitive type reactive power. It is more than 3 times overpriced above price of typical inductive var'. And inductive var's are also not so cheap. Energetic companies cant charge private homes for using reactive power but still must maintain those var's and they do not like them cuz they stuff their precious transmision lines and limit max power transfer. Company must limt power delivery and by this less money is earn. Especially capacitive vars whose cause transient high currents and especially well stuff wires by this. This lac of charge possibility create a high lobby on various commisions to force use of power factor correctors in many apps and not use capacitive input solutions other than tiny low watt cicuits. Compensation of cap require use of choke so its rather unpractical. Same with ballast. When u consider howhigh priced are capacitive var's r u are forced to compennsate a better less costly solution is always choke alone and other aspect is lack of transient currents whose caps generate when negative differential resistance device is in series with them and such are cfl lamps.

I know, provider dont like "dark energy" but in low parts I dont see a problem. Energy I give back to the net is quite low and might be directly used by my neigbours (minus lost energy over the 2.5qmm wires), and with modern powermeter they can even measure it. I am not up to date how and if they charge me for it and how much... but in todays mobile networks, you pay for receiving bytes via TCP/IP which send some ACKs back to the sender you pay as well for and dont realies them, because you are waiting to finish your gigabyte download ;-)
