The efficiency is very poor with this one (ca. 30%) but thats probably because this simulation is poor in terms of LC-resonance calculations. The frequency and the transformer are both poorly dimensioned such as the capacitor. Optimally the primary would have a perfect sine wave, limited by the wire resistance. The 1MOhm resistor is just for the reference of the simulation but its actually useless.
