Abstract:
An inductive charger that is capable of using both single-phase and three-phase power sources, comprising:a rectifier that can be connected to both single- and three-phase power sources; a capacitor connected across an output of said rectifier; an inverter that is connected to said rectifier and said capacitor and that includes a plurality of switching circuits; a series resonant tank circuit connected to an output of said inverter; a charge coupler and an inductive inlet including a transformer and a parallel resonant tank circuit for coupling energy to a load; and a controller that is connected to said rectifier and said inverter, that generates drive signals for controlling said switching circuits, that operates said inductive charger in a super-resonant mode and that regulates output power to said battery by modulating an operating frequency and output current of said inductive charger around an input frequency and an input current.
