1. A push-pull inverter device, comprising:
- two substantially identical single-ended EF2 inverter sections coupled together with a shared ground and a resonant network that is coupled to at least one load, wherein each inverter section comprises a switching section,wherein the switching sections are switched at a same switching frequency, but with a phase difference of about 180 degrees,and wherein the resonant network is partially shared and independently tuned to an impedance seen by each respective switching section, thereby providing independent tuning of even and odd components of the switching frequency.

Abstract
A switching inverter having two single-ended EF2 inverter sections coupled together with a shared ground and partially shared tunable resonant network that is coupled to at least one load, wherein each inverter section comprises a switching section, and wherein the shared tunable network section allows independent tuning of an impedance seen by the corresponding switching section thereby independently tuning even and odd harmonics of the switching frequency.
