Very Easy and Simple 3.7 Volts DC to 3000 Volts DC circuit using mini step up transformer and voltage multiplier circuit. The step up circuit is driven by Power Mosfet IRFZ48N and a mini-transformer that convert 3.7 volt DC to around 1000 Volt AC then using voltage multiplier circuit to amplify further and turn back into DC using a series of 1N4007 diode.
