What voltage are you starting from, and what voltage do you want to achieve ? Those are critical parameters for selecting a transformer and designing the converter circuit.
My first nixie clocks have *no* transformer, and use a voltage-doubler. Simple & easy to design. Just be careful about live voltages. I've also done a tiny DC-DC converter for a wristwatch, and that was a lot of design and debug work. A good middle-ground if you are doing a custom design is to use a power-transformer with dual primary windings, then use one of the primaries for your HV supply. In the US, the 120V line-voltage will produce +170V when rectified & filtered. This is a bit low for reliable nixie firing over the lifetime of the tube, especially if you use a dropping resistor instead of a constant-current driver. Using a secondary winding you can 'boost' the HV a bit more, or you can use a voltage-doubler though the latter will waste more energy. -- You received this message because you are subscribed to the Google Groups "neonixie-l" group.
