Abstract

Self-tuning controllers for inductive power transfer (IPT) systems based on a simple sliding-mode control (SMC) method is proposed in this paper. The SMCs are designed based on the energyinjection and free-oscillation techniques and they are able to regulate the resonant current around a reference current autonomously. The proposed controllers automatically synchronize the switching operations of the power electronic converters to the resonance current of the IPT system. As a result, this feature eliminates any potential need for manual frequency tuning and maximizes the that we could extract from this system. Also, it enables soft-switching operations (zero-current switching) which will improve the efficiency of the power electronic converters and increase their life span. The proposed SMCs have simple design analog design, using logic gates, of the proposed controller. The proposed controller can be implemented on conventional full-bridge or half-bridge AC/DC/AC converters without a dc-link capacitor. Therefore, using the proposed controller the converters are expected to have a high reliability and extended life time due to the soft-switching operation and elimination of short-life electrolytic capacitors. The soft-switching operation will further reduce switching stress, switching loss and electromagnetic interference (EMI) of the converter system as a whole. Also, it has a simple analog design which enables higher frequency operation, and makes it suitable for IPT applications. The proposed control method is analyzed theoretically, then simulated in MATLAB/Simulink and is implemented experimentally.
