The temperature of the heating element is estimated based on the first and second temperatures using a first equation when the cooling device is inoperative, whereas it is estimated using a second equation when the cooling device is operative, thereby enabling to accurately estimate the temperature of the heating element equipped with the cooling device."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Heating element temperature estimation apparatus","description":"In an apparatus for estimating a temperature of a heating element such as IGBT mounted on an electronic printed circuit board, a first temperature and a second temperature at positions away from the h","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-8483989","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.
