DC to AC oscilator and transformer

[itsjustme]

Hello, can someone please help me out here, i want to step up the voltage of a 1.5V battery to 300V, i know that to do so you need an oscilatro circuit consisting of a transformer a small capacitor and a transistor. so my question is, does the type of transistor/capacitor i use matter?

No, if you use "an oscilatro circuit consisting of a transformer a small capacitor and a transistor" because any transistor and capacitor will withstand 1.5 V.

But the usual way of getting such ratios of voltages is using a flyback circuit ( look at wiki ).

And this is a post for "enginering" !
