• In this paper we present a new circuit design for multi-pickup high-power inductive power transfer systems. The proposed design combines parallel compensated resonant tank with tri-state boost converter. By synchronizing tri-state boost switching period with the half-period of resonant tank voltage, we position the inherently discontinuous current pulse drawn by tri-state boost to control both active and reactive power flow from the resonant circuit to tri-state boost. Controllable reactive current can be used effectively to emulate appropriate inductance or capacitance to tune the resonant tank and achieve optimal power transfer.
