An over-temperature protection system and method for a DC capacitor of an inverter are provided. In the over-temperature protection system, a capacitor generates a DC voltage on both terminals thereof. An inverter converts the DC voltage generated on the both terminals of the capacitor into an AC voltage and supplies the AC voltage to a motor. A controller induces a ripple current of the capacitor based on a driving point determined by a torque and a speed of rotation of the motor and determines whether the capacitor is in an over-temperature state based on a totalized value of the ripple current.
