Abstract:
An inductive charge system may include an inductive charging circuit having a switchgear configured to swap between a step-up converter and a step-down converter. The inductive vehicle charge station or system may include a controller configured to operate the switchgear to switch between the step-up converter and the step-down converter based on presence or absence of a load. The step-up converter may be a boost converter. The step-down converter may be a buck converter. The buck converter may have a maximum power output of 100 W. An output of the step-down converter may include a forward-biased diode to prevent backfeeding. The controller may be further configured to ramp an output voltage of the step-down converter from a coupling voltage to a charging voltage to prevent hard switching between the step-up converter and the step-down converter.
