COMMON MODE FILTER DEVICE AND ELECTRICAL EQUIPMENT |
摘要 |
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). 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. |
