An implanted medical apparatus and external power source use the same coils for energy transfer to the implanted medical device as used for transmission of control signals from the implanted device. In one example, implanted circuitry generates a feedback control signal indicative of the load voltage level of a load-generating medical device and superimposes the feedback sign al on an inductor capacitor (LC) tank circuit for detection by the external powering apparatus. The external powering apparatus uses the feedback signal to control the energy transfer to the implanted medical device, thus regulating the load voltage at the load-generating medical device
