Each conversion device includes: a first conversion unit which has a DC/DC converter including an isolation transformer, and a capacitor, and which converts the inputted DC voltage to voltage containing a pulsating-current waveform corresponding to the absolute value of voltage obtained by superimposing a third-order harmonic on a fundamental wave as the AC waveform to be outputted; and a second conversion unit which has a full-bridge inverter for inverting the polarity of the voltage containing the pulsating-current waveform, per one cycle, thereby converting the voltage to voltage having the AC waveform."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Power conversion device and three-phase AC power supply device","description":"A power conversion device includes: a conversion device for each phase which converts DC voltage inputted from a DC power supply, to voltage having an AC waveform to be outputted to each phase with re","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-9831676","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.
