A resonant circuit couples the first bus converter and the second bus converter. Further, a controller provides switching signals to the first bus converter and the second bus converter to operate the power converter in a soft switching mode. The controller includes a voltage detection circuit connected across at least one switching device of the power converter to detect a device voltage across the at least one switching device and a counter to count a number of hard switching detection pulses of the hard switching pulse signal detector. The controller also includes a calculation module to update the number of hard switching detection pulses of the hard switching instances and to generate a new number of hard switching detection pulses and a comparator to compare the new number of hard switching detection pulses with a threshold value and to provide a control signal if the new number exceeds the threshold value."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"System and method for operating a power converter","description":"A power converter includes a first bus converter for converting a first direct current (DC) bus voltage into a first high frequency alternating current (AC) voltage and a second bus converter for conv","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-9667157","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.
