    Patent number: 9660443
    Abstract: Control circuits with energy recycling for envelope elimination and restoration and related methods are disclosed. A control circuit includes a filter module configured to condition an input power signal to provide an output power signal. An energy recapture module is electrically coupled to the filter module and is configured to capture a portion of residual energy from the filter module and return the portion of the residual energy to the input power signal. A control module is electrically coupled to the filter module and the energy recapture module and is configured to control the filter module to provide the output power signal and is further configured to control the energy recapture module to capture and return the portion of the residual energy to the input power signal.
