Electronic device and control method thereof

A dryer comprising:

• a drum configured to accommodate an object to be dried;
• a hot air supply device configured to supply hot air into the drum;
• a motor configured to rotate the drum;
• a power supply device configured to supply power to the motor;
• memory, comprising one or more storage media, storing instructions;
• and
• at least one processor configured to control the motor and communicatively coupled to the drum, the hot air supply device, the motor, the power supply device, and the memory,
• wherein the power supply device includes:
• a power terminal unit configured to receive alternating current (AC) power including a ground wire through a first input terminal and a second input terminal,
• an electro-magnetic interference (EMI) filter configured to remove noise included in the AC power, and
• a ground terminal including the ground wire connected to the power supply device, and
• wherein the EMI filter includes:
• an X capacitor unit including a first capacitor,
• a first common mode filter including a first core, a first inductor wound around the first core, and a second inductor wound around the first core,
• a Y capacitor unit including a second capacitor and a third capacitor connected in series, and
• a second common mode filter including a second core, a third inductor wound around the second core, a fourth capacitor connected in parallel to the third inductor, a fourth inductor wound around the second core, and a fifth capacitor connected in parallel to the fourth inductor.
