Abstract
First and second resonant circuits store energy from a supply. First and second switches are respectively coupled to the first and second resonant circuits for generating resonant oscillations in the resonant circuits. A deflection circuit coupled to one of the resonant circuits has energy transferred to the deflection circuit during the resonant oscillations. A control circuit coupled to the switches varies the conduction angle overlap of the resonant oscillations in the resonant circuits for providing energy regulation.
