Application of Contactless Inductive Charging for Ship—A Review

The research review the application of contactless inductive charging for marine applications. Contactless power transfer (CPT) is the method to transfer power between two separately coil that known as primary and secondary winding. The CPT system is built from main component of winding that separated from primary and secondary winding through a large air gap for battery charging application. The principle of resonance is used to increase the efficiency of power transfer through large air gap between the winding. In addition, the compensation network is applied in primary and secondary winding of the CPT transformer to reduce VA rating and increased power transfer capability of the CPT system. Next, marine electrical propulsion and energy storage system such as battery, super capacitor, flywheel and super conducting magnetic energy storage will be discussed. The advancement of electrical propulsion ships make it reliable to the ship power system in term of fuel economy, and reduced emission and at the same time meet the increasing of power demands.
