Abstract: A voltage quality module (VQM) function and a solar power generation function are integrated by sharing a single voltage converter (VC) within the electrical system of an automotive vehicle with an electric-start internal combustion engine. The cost of adding solar power generating capabilities to vehicles, the packaging complexities of the systems, and the number of added components are all decreased. The VC can be a DC-DC converter in a boost mode or a buck mode. A switching circuit selectably couples the VC between a main battery and an accessory bus or to between a solar panel and an auxiliary battery. A VC controller regulating a VC output using the main battery to stabilize an accessory bus voltage when in an engine crank mode and otherwise regulating the VC output to match an auxiliary battery voltage using the solar panel output.

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.
