Abstract
Inductance and Q factor of the ferrite-core shielded power inductors are extracted from two-port S-parameter measurements in the frequency range from 500 kHz to 100 MHz. Seventeen power inductors are chosen to investigate the impact of the different manufacturer, inductance and saturation current rating on the extracted characteristics. The impact of the inductance and Q factor on the operation of the class-E resonant converter is analyzed by the time-domain simulations. The output voltage of the converter largely depends on the Q factor and inductance of the power inductor used in the design methodology.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
