Communication is crucial for Dual Side Control (DSC) of Inductive Power Transfer (IPT), which uses multiple variables in two separate converters for efficiency optimization. To avoid add-on communication systems, this letter proposes to implement Talkative Power Conversion (TPC)-added utility communication by modulated power conversion without intrusive changes to hardware, control or power conversion. The secondary converter is used to transmit feedback information and the Phase Locked Loop (PLL) typical of synchronous DSC is relocated to the primary side as the receiver, avoiding hardware additions. Based on Continuous Phase Frequency Shift Keying (CPFSK), the communication process is then designed to act as quasi steady state to the power transfer and control processes. The strategy is demonstrated to actively close a DSC loop in experiment with an average frequency shift of only 0.15 Hz. No added perturbations are visible in time domain voltage or currents, which confirms the nonintrusive nature of the proposed method.
