摘要： An integrated converter is provided. The integrated converter includes a high-voltage charger having a power factor correction (PFC) device configured to compensate a low-frequency ripple and convert an alternating current (AC) voltage of a commercial power source into a direct current (DC) voltage. A first switching module is configured to convert the DC voltage output from the PFC device into an AC voltage and charge a high-voltage battery using the commercial power source and a low-voltage charger that is connected between the PFC device and the first switching module and the high-voltage charger configured to charge a low-voltage battery using the commercial power source or the high-voltage battery.

摘要： Disclosed are DC-to-AC converter control methods, ground assemblies and wireless power transfer methods using the same. A method for controlling a DC-to-AC converter of a ground assembly used for wireless power transfer, which includes first, second, third, and fourth switches arranged in a form of a bridge circuit between a power source and a primary coil, may comprise detecting a current flowing through the primary coil at a rising edge of an output voltage signal of the DC-to-AC converter; determining whether a strength of the current is at a negative level which falls within a predetermined reference range; and in response to a determination that the current is not at the negative level, changing switching frequencies of the DC-to-AC converter.

摘要： A vehicle battery system and a method of controlling the same are provided. When voltage of the vehicle battery is different from an output voltage of a commercially available quick charger, two high-voltage batteries are connected in parallel during battery charging, and the two high-voltage batteries are connected in series during vehicle driving. Accordingly, a compatibility problem is resolved, thereby allowing an inverter, an electric motor, and a connector to have increased efficiency and to maximize a reduction in size, weight, and material cost thereof.
