Charging apparatus for electric vehicle

A charging apparatus for an electric vehicle, comprising:

• a motor configured to generate power required to drive the electric vehicle;
• an inverter configured to supply power to the motor;
• an alternating current (AC) power input terminal configured to receive at least one of single-phase AC power and multi-phase AC power;
• a power factor corrector having a single three-leg half bridge circuit configured to receive the AC input power through the AC power input terminal;
• a link capacitor configured to be charged through at least one of combinations of the power factor corrector, the motor, and the inverter;
• a switch network having at least one switch configured to selectively connect the AC power input terminal to the power factor corrector, the link capacitor, the motor, or the inverter;
• and
• a controller configured to operate the power factor corrector, the switch network, and the inverter based on a condition of AC input power received through the AC power input terminal,
• wherein the switch network further includes:
• a first switch disposed between the link capacitor and the inverter;
• a second switch disposed between the inverter and a battery;
• and
• a third switch disposed between any one of three legs of the power factor corrector and the inverter.
