Passive circuits for power factor correction (PFC) are simple, reliable, robust, and they don't generate EMI [1-4]. Plus, they offer a low-cost alternative for complying with harmonic current limit ...

Inductors range from RF coils used in communications through switchmode inductors used in power supplies and differential and common mode inductors in EMI filters. As switchmode power supply designs ...

Air core inductors exhibit high Q, maintain a constant inductance value regardless of current, and can be tuned to specific inductance values by manipulating the distance between coil windings. They ...
