The LC filter includes an inductor, capacitor, and a coil positioned and oriented relative to and electrically connected with the capacitor. The coil positioned with the capacitor provides the ripple current caused by operation of the switching circuitry to flow through the capacitor and coil with opposite direction. The ripple current flowing through the coil attenuates a magnetic field generated by the capacitor while reducing parasitic inductance of the capacitor."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Method and apparatus for coupling cancellation","description":"A DC to DC power converter includes a switching circuit and an LC filter configured to reduce parasitic inductance.
