Zero voltage switching series resonant half bridge VHF inverter

A DC to AC inverter comprising:

• a first capacitor and a first inductor connected in series between a first supply voltage node and a central node, said first supply voltage node being at a positive voltage relative to ground;
• first switching means connected across said first capacitor, said first switching means being driven with a first periodic drive signal of a predetermined frequency;
• said first capacitor and said first inductor comprising a first resonant circuit that is configured to have a close to zero voltage across the first capacitor when the first switching means is switched to a conductive state;
• a second capacitor and a second inductor connected in series between a second supply voltage node and the central node, said second supply voltage node being at a voltage that is less than said positive voltage;
• second switching means connected across said second capacitor, said second switching means being driven with a second periodic signal of said predetermined frequency and being out of phase by 180 degrees relative to said first periodic drive signal;
• said second capacitor and said second inductor comprising a second resonant circuit that is configured to have a close to zero voltaqe across the second capacitor when the second switching means is switched to a conductive state;
• and
• wherein said first and second inductors prevent rapid buildup of current through said first and second switching means.
