Re: Reg:Boost Converter
Portable color TVs before LCD became popular used glass CRTs which ran on 20KV or more and they were powered from 12V.
With very careful design you can generate extremely high voltages, certainly in the 100KV regions from very low voltages. But please remember you don't get something for nothing, the total output POWER is always less than the power you consume to generate it. Power is calculated by multiplying the applied voltage by the current drawn (W=V*I). For example, assuming 100% efficiency, which you would never reach, 12V with 1A being drawn could produce 12KV but only at a current of 1mA. As the voltage is stepped up more and more the efficiency tends to drop so in practice you would get considerably less current out.
