A primary coil current that flows through a primary coil of the transformer, and a secondary coil current that flows through a secondary coil of the transformer are detected. The current difference between the detected primary coil current and the detected secondary coil current is calculated. Based on the calculated current difference, the cycle of ON/OFF periods of four arms provided on the transformer coupled booster is maintained at a constant level. Control is carried out so that the ratio of the first arm's ON period to the OFF period is always equal to the ratio of the third arm's ON period to the OFF period."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Switching control method of transformer coupled booster for suppressing an increase in energizing current","description":"Provided is a switching control method of a transformer coupled booster to suppress an increase in energizing current in a transformer of the transformer coupled booster and downsize the transformer c","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-8493756","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.
