Super-lift DC/DC converters

With DC transmitted at higher voltages over long distances proving to be cheaper than AC transmission, research in finding newer ways of increasing the DC voltage at lesser cost and higher efficiency has been of high priority in this era. Keeping in mind the performance of non-linear elements and th...
