How does it Work? Common Mode Chokes - Pulse Electronics
the common mode signal that enters or leaves a PCB. X and Y capacitors are commonly used to shunt the common mode noise away from the circuits of interest, while a common mode choke is used to attenuate or dampen the noise. When placing an inductive component such as a choke in the path of current, there are a few key items one must consider.

A NOVEL DESIGN FOR A 3.6KW LLC TRANSFORMER WITH …
www.pulseelectronics.comIntroduction The LLC Converter The LLC Transformer The benefits of the LLC topology for multi-KW On Board Charger (OBC) applications are well understood with the resonant inductor facilitating zero volt switching operation. The LLC transformer leakage inductance can replace a discrete resonant inductor if the value can be correctly sized and

www.pulseelectronics.comIf a particular tool cannot design differential traces, it is permissible to specify 55 Ω to 65 Ω single-ended traces as long as the spacing between the two traces is minimized. As an example, consider a differential trace pair on Layer I that is 8 mils (0.2 mm) wide and 2 mils (0.05 mm) thick, with a spacing of 8 mils (0.2 mm).

Any real transformer will have a small, but non-zero capacitance linking primary to secondary windings. The capacitance is a result of the physical spacing. For common-mode current, Cww offers a path across the transformer, the impedance of which is
