*2011.07.14 Some tests by Nikos, using mosfet driver [http://search.digikey.com/scripts/dksearch/dksus.dll?Detail&name=MC34152PGOS-ND MC34152] + TO220 Mosfet+Generator
:Output capacitor 100uF according to schematic
:Attention 5V max from Generator to MC34152
 Minimum Duty Cycle tested: 5%. Lower needed. It seems that the principle of switching to GND works. To proceed with comparator and close the loop
