The driving control unit controls the carrier frequency on the basis of a noise level of a carrier noise obtained by combining noises that occur in the electric motor and the power converting apparatus due to the driving of the MOS-FETs at the carrier frequency and a noise level of driving noises from a plurality of noise sources that occur irrespective of the carrier frequency in the same housing in which the power converting apparatus and the electric motor are contained."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Power converting apparatus, dehumidifier, air conditioner, and refrigeration apparatus","description":"A power converting apparatus outputs an alternating-current power to drive an electric motor, and includes: a switching circuit that converts an input direct-current power to an alternating-current po","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-9825575","license":"CC-BY-4.0-like","license_terms":"AI-generated analysis on this page (summary, layman_explanation, technical_analysis, business_analysis, faqs) may be reused with attribution and a visible link back to the canonical URL above.
