Beschreibung
Zusammenfassung:	A surge protection circuit includes: a power supply unit configured to supply first power, a filter unit configured to filter noise of the first power while a current corresponding to a surge flows through the filter unit, a motor unit provided with at least one motor, a control unit configured to control the motor unit according to an operation mode, and a rectification unit provided with at least one protection capacitor and configured to rectify the filtered first power into second power. The filter unit is connected with a ground to thereby apply the current to the filter unit through the ground. A first impedance is generated by the filter unit and the rectification unit and a second impedance is generated by the control unit and the motor unit and a value of the first impedance is less than a value of the second impedance.
