Abstract:
1. An electromagnetic interference suppressing apparatus for a high-frequency signal generation device, the high-frequency signal generation device comprising 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 wherein said capacitive or inductive coupling allows the alternating current to pass through while insulating the direct current and allows the high frequency to pass through while blocking the low frequency and wherein the electric conductor is short-circuited to the reference zero voltage point of the high-frequency signal generation device and the interference voltage formed by the high-frequency interference signal together with the reference zero voltage point forms a loop circuit and is converted into an internal load of the high-frequency signal generation device.
