A charging apparatus and an electric vehicle including the same are disclosed. The charging apparatus includes a rectifier to rectify input alternating current (AC) power in a charging mode, an interleaved buck-boost converter to convert the rectified power into direct current (DC) power to supply the converted DC power to a battery, the interleaved buck-boost converter including a plurality of buck-boost converters, and a converter controller to control the interleaved buck-boost converter, wherein a first buck-boost converter of the interleaved buck-boost converter includes a first buck switching element connected to the rectifier, a first boost switching element, an inductor connected between the first buck switching element and the first boost switching element, a first diode connected in parallel between the first buck switching element and the inductor, and a second diode connected between the first boost switching element and an output of the interleaved buck-boost converter.

Charge apparatus and electric vehicle including the same

An inverter stack includes an enclosure on which an inlet port is formed at a lower end thereof and an outlet port is formed at an upper end thereof, the enclosure defining an internal space, a heat sink having a switching element, disposed within an upper region of the internal space, and a plurality of DC-link capacitors disposed within the internal space and below the heat sink. Through this, heat generated in high heat dissipation components is immediately moved upward by convection, thereby suppressing the damage of components due to high temperature.

Inverter stack

Provided is a power module in which a motor and a motor driving unit are efficiently configured and a vehicle having the same. The power module includes a power module case forming an external form; an inverter provided within the power module case and configured to convert a direct current (DC) power into an alternating current (AC) power; an AC power conductor provided in the power module case and connected to the inverter to cause the AC power converted by the inverter to flow therethrough; and a motor provided in the power module case and connected to the AC power conductor to receive the AC power and generate a rotational force.

Power module and vehicle having the same

An apparatus for driving a motor of an electric vehicle is provided. The apparatus includes a capacitor supplied with power by a battery; an inverter configured to include a plurality of switching elements, convert direct current (DC) power stored in the capacitor into alternating current (AC) power in accordance with the switching of the switching elements and drive a motor with the AC power; and a capacitor protector provided between the battery and the capacitor and configured to consume initial power supplied by the battery at an early stage of the supply of power by the battery, the capacitor protector including a common resistor that consumes the DC power stored in the capacitor when the capacitor is discharged. Therefore, it is possible to guarantee the reliability of the apparatus.
