Claim Text:
1. A method, comprising: providing a circuit including: a source of positive dc voltage connected to a first inductor which is connected to a first variable capacitor (VC) which is connected to a second VC which is connected to a second inductor which is connected to a source of negative dc voltage, wherein said first VC and said second VC are synchronously monotonically variable between a maximum gap and a minimum gap, wherein said first inductor in series with said first VC forms a first series-resonant circuit, wherein said second inductor in series with said second VC forms a second series-resonant circuit, wherein each of said first series-resonant circuit and said second series-resonant circuit are configured to comprise a resonant frequency that varies over a band of frequencies that includes the operating frequency of said first VC and said second VC; a first coupling capacitor (CC) connected to a node between said first inductor and said first VC; a second CC connected to a node between said second inductor and said second VC; and a load connected between said first CC and said second CC; determining a target voltage at said minimum gap, wherein said target voltage is a specific voltage that is less than the breakdown voltage at said minimum gap; and simultaneously maintaining said target voltage at said minimum gap while synchronously adjusting the value of said first CC and said second CC to move the peak phase of the generated voltage to a new position to produce an increased allowable voltage due to an increased breakdown voltage at said new position relative to the allowable voltage at said new position prior to the step of adjusting the value of said first CC and said second CC.
