The motor drive control device turns off a lower arm switching element for a largest phase by causing a first PWM pulse based on a largest phase voltage command and a carrier signal throughout an entire first period during which the carrier signal rises or falls to be at a low level. The motor drive control device turns on a lower arm switching element for a smallest phase by causing a second PWM pulse based on a smallest phase voltage command and the carrier signal throughout an entire second period during which the carrier signal rises or falls to be at a high level."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Motor drive control device, motor system, and air blowing device","description":"A motor drive control device controls driving of a motor by performing PWM control of turning on-off of an arm switching element of a PWM inverter outputting a three-phase AC voltage to the motor, and","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-11515826","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.
