Those terms are rather imprecise because all diodes willl rectify. The major difference is the amount of forward voltage they require to conduct. A silicon diode will require 0.65 to 0.72 Volts when fully conducting, but the Schottky, being of a different constructionhas a lower forward voltage in the range of 0.2 to 0.4 Volts. This would seem to be a major benefit given the low value of your voltage source. At some point in the battery discharge cycle there won't be enough voltage to sustain the operation.Ok, you modified the circuit, now it makes sense, do I need a simple diode or rectifying diode ? the post #20 circuit will charge the cap to 250V ?
I'm reluctant to say anything further based on the concept that charging a capacitor to 250 Volts seems like a less than prudent course of action. If the TS is bound and determined, he can do it on his own for which none of us need be responsible.It simpler if you just draw me the circuit that's charging the cap to 250V post #5 and #20 seem close.
SUCH FEAR!!I'm reluctant to say anything further based on the concept that charging a capacitor to 250 Volts seems like a less than prudent course of action. If the TS is bound and determined, he can do it on his own for which none of us need be responsible.
Not everybody has the good sense to take precautions.SUCH FEAR!!
Charging a cap to some higher voltage for a flash system or a magnetic pulse system or to drive an acoustic sounder is totally reasonable. The world does not run on 3.3 volts DC!
Of course, a system to charge a car body to 10 KV to deter carjackers with guns would not be supported here, but that is very much different.
