    Common Mode Choke

    Common Mode Chokes When we said a common mode choke, it means it was wound both line and neutural windings on a single core. Since the noise would be common mode noise usually, the way to lower (if not eliminate) the unwant noise frequencies is to use a common mode choke As below picture show us details of Common-Mode Signals Defined: Such signals can arise from one or more of the following source...

    Flat Wire Transformer Horizontal Plate Common Mode Chokes Line Filter

    Comparing round copper wire, flat copper wire with more excellent performance, higher current ( unit current density reach 1.5~2.0 times) & smaller volume (0.5~1.0 times). Lower DC resistance, extremely small capacitance distribution, perfect heat dissipation. Closed magnetic circuit design, small magnetic leakage, stable impedance balance, good conducted radiation effect and EMI effect. Autom...

    The reasons that inductance can eliminate EMC

    During EMC power supply circuit design, common-mode interference is the most difficulties encountered, common mode inductor is one of the major methods on solving interference signals. Here let's talk about the basic principles of solving EMC artifacts from design plan in this way. A common mode inductance, is wound both line and neutural windings on a single core. While the magnetic flux in ...

    Dicuss about Four-Phase Common Mode Choke

    The four-phase common mode choke is a four-terminal device, which founded by a nanocrystalline magnetic toroidal core as a common mode interference suppression device, four sets same size, same turns numbers coils wound symmetrically. When the common mode current flows, the magnetic flux in the magnetic ring superimposes each other, resulting in a considerable inductance, which has a suppressing e...
