• battery-resistance meter
• refrigerator economizer
• From Elektor 1998.03: /Schematics/Power supply/Power supply 0-24V 1A or 2A

• BUK455 100 V, 26 A, 125 W, 0.1 Ohm, 1650 pF, For switching applications. *Obsolete*
• 2011.07.14 Some tests by Nikos, using mosfet driver 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
