The system also includes a plurality of inductors, with at least one inductor coupled between a midpoint of each bridge leg and an LCL filter, the inductors in each phase leg being magnetically coupled. The system further includes a control system to drive the power inverter in a soft switching configuration, the control system programmed to output a switching signal to the power inverter according to a duty cycle and a phase shift angle, determine a value of the duty cycle, and optimize the phase shift angle of the power inverter based on the value of the duty cycle."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"System and method for soft switching power inversion","description":"A power inversion system includes an input and output coupleable to a DC power and an AC load, respectively, and a power inverter including a plurality of phase legs each having two bridge legs couple","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-9705422","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.
