摘要： Disclosed herein is a charging apparatus for an electric vehicle. The charging apparatus includes a motor generating a power for vehicle driving. An inverter supplies a power to the motor. An alternating current (AC) power input stage receives an AC input power from among a single-phase AC power and a multi-phase AC power. A power factor corrector includes full bridge circuits receiving the AC input power through the AC power input stage. A link capacitor is charged through a combination of the power factor corrector, the motor, and the inverter. A switch network has a first switch connecting one of an AC power input line and a neutral line of the AC power input stage to the power factor corrector and a second switch selectively connecting the AC power input stage to the power factor corrector or the link capacitor. A controller operates the power factor corrector and the switch network based on a received AC input power condition.

摘要： A charging apparatus for an electric vehicle has a small-sized simple structure, and charges a battery of the electric vehicle upon receiving electricity from various kinds of power sources. The charging apparatus includes a motor, an inverter, an AC power input stage, a power factor, a link capacitor, a switch network, and a controller. The AC power input stage receives an AC input power from a single-phase AC power or a multi-phase AC power. The power factor corrector has a single three-leg half bridge circuit receiving the AC input power through the AC power input stage, and the link capacitor is charged through at least one of combinations of the power factor corrector, the motor, and the inverter. The controller controls the power factor corrector and the switch network based on a condition of AC input power received through the AC power input stage.

摘要： A charging apparatus for an electric vehicle is provided. The apparatus includes an AC power input terminal receiving one AC input power from among single-phase AC power and multi-phase AC power. A power factor corrector having full bridge circuits receives the AC input power through the AC power input terminal. A link capacitor is charged through the power factor corrector. A first switch connects any one of an AC power input line and a neutral line of the AC power input terminal to the power factor corrector and a second switch selectively connects the AC power input terminal to the power factor corrector, or the link capacitor. The power factor corrector and the switch network operate based on a condition of received AC input power. The second switch includes a third switch and a fourth switch that connect each full bridge circuit to a positive battery electrode.

摘要： A vehicle electronic module is provided. The vehicle electronic module has a reduced size and improved productivity by replacing a sensor and an offset unit of an electromagnetic interference (EMI) filter module with a printed circuit board (PCB) winding structure. The electronic module includes a sensor that detects EMI noise of a power line and an offset unit that transmits an offset voltage for removing the EMI noise to the power line. A controller is configured to generate the offset voltage that corresponds to the EMI noise detected by the sensor. Then sensor and the offset unit are formed in a stacked structure of the PCB.
