Claim 7:
8. A method for controlling a high voltage generator, the high voltage generator comprising:
an inverter bridge, the inverter bridge comprising a first bridge leg and a second bridge leg;
a first resonant branch, the first resonant branch being coupled with the first bridge leg;
a transformer coupled in series between the first resonant branch and the second bridge leg;
a second resonant branch, the second resonant branch being coupled in parallel with the transformer, wherein the second resonant branch includes a capacitor and an inductor connected in series;
a rectifier circuit, the rectifier circuit being coupled with the transformer for providing output voltage;
the method comprising:
controlling the phase relationship between the bridge leg voltage and the output current of the inverter bridge to control a frequency of a driving signal of the inverter bridge.
