EMI FILTER REDUCING CONDUCTIVE NOISE |
摘要 |
PURPOSE: An EMI filter for reducing a conductive noise is provided to remove the conductive noise due to a switching operation by arranging ferrite beads on both sides of a capacitor. CONSTITUTION: Both ends of a first capacitor(C1) are connected to a first input terminal(111) and a second input terminal(112). The first input terminal is connected to an active line of an AC power source. The second input terminal is connected to a neutral line of the AC power source. A ferrite bead(B1, B2) is formed on both sides of the first capacitor. A line filter(13) has first and second coils(L1, L2). The first and second coils are connected to the first input terminal and the second input terminal. One sides of a second capacitor and a third capacitor are connected to the other sides of the first and second coils. The other sides of the second and third capacitors are grounded.
