The voltage converter includes a first sub-converter having a first switch half-bridge, which is coupled to a first pole of the input voltage by a first main coil, and a second sub-converter having a second switch half-bridge, which is coupled to the first pole of the input voltage by a second main coil. In addition, the voltage converter includes a diode half-bridge, which is jointly used by the first sub-converter and the second sub-converter. The voltage converter has a first return coil and a second return coil, which couple a center point of the diode half-bridge to a second pole of the input voltage. The first and second main coils and the first and second return coils form a coupled choke, the coupled choke having a choke core. The choke core has at least one outer leg, which is surrounded by windings of the first and/or second main coil and/or of the first and/or second return coil, and at least one center leg, which is not surrounded by windings of the main coils or of the return coils. The outer leg and the center leg have materials with different permeabilities."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Voltage converter having coupled PFC choke","description":"A voltage converter is designed to convert an alternating input voltage into a direct output voltage.
