Abstract:
1. A system comprising: a switching network module when operationally configured, receives a DC signal and outputs a first square wave signal and a second square wave signal; a resonant tank module, coupled to the switching network module, said resonant tank module when operationally configured, receiving the first square wave signal from the switching network module and the second square wave signal from the switching network module, wherein the first square wave signal is out-of-phase with respect to the second square wave signal, said resonant tank module effective to convert a signal from the switching network module into a first analog signal and a second analog signal, wherein the first analog signal and the second analog signal are out-of-phase; and a current sense module, coupled to the resonant tank module at a third node, effective to accurately sense current through a load, wherein the load is operationally connected to the resonant tank module in a floating drive configuration and the load is driven by the first analog signal at a first end and by the second analog signal at a second end, wherein the third node is different from and not connected directly to the first end and the second end.
