Instrument Voltage Transformers (IVTs) introduce errors in power quality measure due to resonance's effects at high frequency. The accuracy of IVTs, definite by standards, is only about nominal frequency and does not consider high frequency response. The paper reports the IVTs experimental analysis on resonance's disturbances transferred to secondary side of Instrument Voltage Transformer. In particular...
In this paper, we have analyzed the behaviour of a switched mode power supply (flyback) in radiated near-field. We have modelled it by equivalent diagrams representing electric operations, including the parasitic elements. First, we have tried to link the amplitude of the spectra of the radiated magnetic field with the electrical quantities (current and voltage) during the different working phases...
The effects of leakage inductance of the output transformer of a current-resonant parallel converter on the latter's characteristics were studied through simulations and experiments. As a parasitic resonance appears between the leakage inductance and the resonance circuit capacitor during the commutating period of the output rectifying circuit every half-cycle, the larger the leakage inductance and...
