Inductive Power Transmission (IPT) systems are widely used to charge mobile devices. In this paper, we propose a design of an IPT system circuit based on an AC-AC converter and semi-Active rectifier. This system shows a higher efficiency in comparison to diode-based rectifiers on the receiving side. In addition, it delivers a constant load current and pure sine-wave signals and has a simple implementation in comparison to inverter-based sending side circuits. The semi-Active rectifier shows a good compromise in terms of efficiency, circuit size, complexity, and controllability. A Proportional-Integral (PI) control algorithms developed for the receiving side to control the semi-Active rectifier to reach a constant load current. Simulation results validates the proposed concept performances by illustrating that the system efficiency reached more than 80% while using the semi-Active rectifier rather than about 60% using the uncontrolled rectifier.
