Frequency response: Resonance, Bandwidth, Q factor
ocw.mit.edu• Therefore at the resonant frequency the impedance seen by the source is purely resistive. • This implies that at resonance the inductor/capacitor combination acts as a short circuit. • The current flowing in the system is in phase with the source voltage. The power dissipated in the RLC circuit is equal to the power dissipated by the ...

www.qsl.net• The resonant frequency is getting by equating the magnitudes of the L and C reactances (X L = X C) Quality-Factor ... • For DC circuits, maximum power will be transferred from a source to its load if the load resistance equals the source resistance. A simple proof of this theorem is given by the following example:

pdfserv.maximintegrated.comConverter Power Supplies Nov 12, 2001 Abstract: The flyback dc-dc converter topology results in significant cost and space savings for multiple output power supplies with high output voltage for power levels up to 100W. Flyback topologies store and transfer energy using a transformer, which due to physical limitations can cause large voltage
