The transformers are dedicated to sensing a common mode current and injecting compensation currents driven by the current control circuit. The transformers provide electric isolation between the current control circuit and power-transferring connections of the common mode filter device. Continuing operation of an electrical apparatus which is power-supplied through the common mode filter device is also ensured in case of failure of the current control circuit, with the LC-filters still producing partial common mode filter function."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Common mode filter device and electrical equipment","description":"A common mode filter device (2) comprises two LC-filters (21, 22) which are serially connected, two transformers (23, 25) and an active current control circuit (24).
