<p>The present invention relates to a vehicle power supply apparatus and, more specifically, to a vehicle power supply apparatus to generate a three-phase alternating current power using different carrier frequencies. To accomplish the above purpose, the vehicle power supply apparatus according to an embodiment of the present invention comprises: a motor to drive the vehicle; a battery to supply power to the motor; an inverter positioned between the motor and the battery, and supplying the power to the motor when converting direct current power from the battery into the three-phase alternating current power (U, V, and W) based on the different carrier frequencies; and a PWM switching controller providing the different carrier frequencies for the inverter.</p> |
