Description
Summary:To improve the efficiency of contactless power transmission (CPT) and the operation stability of ultrasonic vibration system, an improved design method for key parts of the contactless power transmission system was proposed and studied. By integrating both inductor model and mutual inductance model, as well as considering the fringing flux effect introduced by the air gap, this design method would be more accurate and reasonable. Considering constraint conditions, such as the operating flux density of the core, mutual inductance between primary and secondary coils, electrical signals loaded on ultrasonic vibrator, the coils and cores were designed. Simulation and experimental studies which were developed on flux density, mutual inductance and amplitude output ability of the system, verified that the key parts of CPT system could stay stable during operation and the CPT system was able to transfer ultrasonic energy efficiently.
