Abstract

This paper explains the development of a wireless power transfer system, whereby inductive coils and power converters, charge an embedded energy-storage system in a microinverter, using a photovoltaic panel. A detailed analysis of the design, implementation and control of a station for battery charging, using a PV panel of 35[W] is developed. An inductive-coupling link is used, which consists of transmitting electrical power from a power source to a load using a magnetic field. Finally, the results obtained in simulations from PSIM software and the experimental implementation are contrasted, showing a 12[V] battery which emulates the embedded energy-storage system to prove the concept. Then, the battery is charged with a controlled current of 300[mA].
