Power converting apparatus and home appliance including the same

A power converting apparatus comprising:

• a rectifier configured to rectify input AC power;
• a converter including a switching element;
• a DC-link capacitor connected to an output terminal of the converter;
• and
• a converter controller configured to control the switching element;
• wherein the converter controller performs spread spectrum modulation (SSM) in which a switching frequency of the switching element is varied within a designated range, and performs active compensation based on real-time switching frequency information of the switching element.

A home appliance including a power converting apparatus, the power converting apparatus comprising:

• a rectifier configured to rectify input AC power;
• a converter including a switching element;
• a DC-link capacitor connected to an output terminal of the converter;
• and
• a converter controller configured to control the switching element;
• wherein the converter controller performs spread spectrum modulation (SSM) in which a switching frequency of the switching element is varied within a designated range, and performs active feed-forward compensation to eliminate a time-varying variable added to the input current in response to the performing of the spread spectrum modulation.
