Claim 12:
13. A high voltage generator, comprising:
an inverter circuit coupled to receive a direct-current (DC) input voltage, wherein the inverter circuit includes a first bridge leg and a second bridge leg;
a resonant circuit coupled to the inverter circuit, wherein the resonant circuit includes a first resonant branch coupled in series to the first bridge leg and a second resonant branch coupled in parallel with a transformer;
the transformer coupled in series between the first resonant branch and the second bridge leg, and also coupled to a rectifier circuit, wherein the rectifier circuit is configured to provide a high voltage output, wherein the second resonant branch includes a second capacitor and a second inductor connected in series; and
a phase control circuit coupled to receive a voltage across and a current through the resonant circuit and also coupled to the inverter circuit, wherein the phase control circuit generates control signals to drive the inverter circuit, and wherein the control signals drive the inverter circuit to keep the resonant circuit operating in an inductive region.
