The calculation unit (40) obtains the across voltage (VL) of the reactor (29) using detection results (Vac1, Vac2) of the voltage detection circuit (33), and estimates a power source current (Iin) based on the across voltage (VL). The calculation unit (40) corrects gains of the detection results (Vac1, Vac2) so that a value correlating with an average value per predetermined time period of the estimated power source current (Iin) matches a value correlating with an average value per the predetermined time period of a current (Iinv) downstream of the capacitor (26), and obtains the across voltage (VL) using the detection results (Vac1, Vac2)."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Current estimating device","description":"The voltage detection circuit (33) is a voltage divider circuit including a plurality of resistances (34a to 34c and 35a to 35c) and detects voltages (Vac1, Vac2) correlating with a power source volta","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-10511233","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.
