    • The present utility model relates to an electromagnetic interference suppressing apparatus for a high-frequency signal generation device. The high-frequency signal generation device includes an inverter means which is used for converting a direct current signal into a high-frequency alternating current signal, wherein the electromagnetic interference suppressing apparatus includes an electric conductor which is in capacitive or inductive coupling with the high-frequency signal generation device and is connected to the reference zero voltage point of the direct current signal. With the present utility model, the electromagnetic interference generated by the high-frequency signal generation device may be effectively suppressed in the case where a reliable earthing is not achievable. The present utility model relates also to an electronic ballast having the function of suppressing electromagnetic interference, and a fluorescent lamp of a compact type having the function of suppressing electromagnetic interference.
