Calculation of impedance of a ferrite toroidal inductor – from first principles
A toroidal inductor is a resonator, though it can be approximated as a simple inductor at frequencies well below its self resonant frequency (SRF). Lets take a simple example, a ferrite toroid of rectangular cross section. From the basic definition we can derive the relationship that the flux density in the core with current I … Continue reading Calculation of impedance of a ferrite toroidal inductor – from first principles
