1. A high voltage generator, comprising:
an inverter bridge including a first bridge leg and a second bridge leg;
a first resonant branch coupled in series to the first bridge leg;
a transformer coupled in series between the first resonant branch and the second bridge leg;
a second resonant branch coupled in parallel with the transformer, wherein the second resonant branch includes a capacitor and an inductor connected in series; and
a rectifier circuit coupled with the transformer for providing an output voltage.
