A command modulation section compares the phase voltage commands with each other, to specify a full-on phase or a full-off phase on the basis of the comparison result and then to set the voltage command of the specified phase to a full-on voltage or a full-off voltage, and offsets the voltage commands of the other two phases according to the full-on voltage or the full-off voltage to modulate the voltage commands into voltage commands allowing the line voltage between the other two phases to be kept constant. A PWM signal generation section generates PWM signals by comparing, according to a predetermined rule set in advance, three carrier waves generated by a carrier wave generation section with each of the phase voltage commands modulated by the command modulation section. Accordingly, each of the phase currents can be calculated from a DC input current, so that the efficiency can be improved."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Inverter control apparatus and inverter apparatus","description":"In an inverter control apparatus, a phase current calculation section calculates each of phase currents flowing into a motor by using measurement results of a current sensor, and a voltage command gen","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-9755563","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.
