Series Resonance in a Series RLC Resonant Circuit

Thus far we have analysed the behaviour of a series RLC circuit whose source voltage is a fixed frequency steady state sinusoidal supply. We have also seen in our tutorial about series RLC circuits that two or more sinusoidal signals can be combined using phasors providing that they have the same frequency supply.

High-Frequency Leakage Currents in Medium Power Adjustable ...

Abstract: Low voltage frequency converters (VFCs) for ac drives supplied from isolation terra (IT) mains can produce voltage spikes in the supplying mains. The spikes are minimalized by earthed electromagnetic compatibility (EMC) filter which is built in intermediate circuit of VFC. In adjustable frequency drive (AFD) of medium and high power (up to 1MVV) the voltage spikes cause damages of ...

High Pass Filter Calculator - Learning about Electronics

This passive RC high pass filter calculator calculates the cutoff frequency point of the high pass filter, based on the values of the resistor, R, and the capacitor, C, of the circuit, according to the formula fc= 1/(2πRC).. To use this calculator, all a user must do is enter any 2 values in the field, and the calculator will compute the value of third field.

High-Frequency Ventilation - draeger

High-frequency ventilation (HFV) as a ventilatory therapy has reached increasing clinical application over the past ten years. The term com-prises several methods. High-frequency jet ventilation must be diffe-rentiated from high-frequency oscillatory ventilation (HFOV or HFO). In this booklet I concentrate on high-frequency oscillatory ventilation.

Utility frequency - Wikipedia

The utility frequency, (power) line frequency (American English) or mains frequency (British English) is the nominal frequency of the oscillations of alternating current (AC) in an electric power grid transmitted from a power station to the end-user.In large parts of the world this is 50 Hz, although in the Americas and parts of Asia it is typically 60 Hz.
