I found this circuit from here and have been thinking about to build it:
Q: My main concern is, whether it is safe to use electrolytic capacitor for C6?
My thinking says, the polarity will get reversed for C6 when MOSFET is turned off. Then if there is no load, electrolytic capacitor is going get damaged/exploded?
Also, chance for MOSFET get damaged because of absence of flyback diode?
