Transforming Voltage and Current

I have been thinking of various modes of transforming electricity . At the higher end we have coil transformers like power & distribution type. One is step up while the latter is step down .They follow Faradays principle and Lenz's law .  You can also step up using a series of diodes for lower voltages .  Further inductance and capacitance can be used in buck and boost transformers . Also I understand for a DC to DC transformation you can first rectify the AC to DC , chop it and then transform using either the isolated or non-isolated type.  An op amp multiplies DC with the help of AC .  It would be nice to develop a set of rules to figure out which criteria would be the best for which use.  Also to know the finest transformer companies in India and the world and their latest developments .  I can think of Texas Instruments ,Infineon , Alsthom, Vishay and the like .  Invite you to contribute to this discussion 

Ruminating on Life ...1

A weekend is a good time to ponder and ruminate on the basic philosophy of life. I do read up on the Bhagavad Gita and Vedanta Treatise every morning before breakfast. Few messages keep appealing to me ...this Life is a Dream and all of us are actors in a play. Hence there is no point getting too caught up with trivial matters. At the same desires are like poison and temptations the snake in them ,which when given rise to can kill us. This is similar to the snake with 5 heads in the Yamuna which Lord Krishna helped to get rid of. Another important element we need to fight is our Ego ...this is akin to the clothes of the Gopis left behind on the riverside which Lord Krishna withheld.The Gopis symbolize all devotees of Lord Krishna on earth and the clothes their ego.In order to reach God one needs to leave behind their ego . The other books I have been recently reading is Meditations by Marcus Aurelius , Epictetus' Manual of Life , the Tripura Rahasya suggested by my friend Ansh
