Going beyond the analysis, a more sensitive measure of exponential decay is -&I/€ = d[ln &(x)]/dx. This is 1 times the x-dependent slope (in dB/cm) of &(x) when graphed in dB. Thus, -&I/€ is the local exponential decay rate of &. For the pulses of Figs. 1 and 2, the computed -&I/& varies from 1185-1257/m (51-55 dB/cm) for the first 60 dB of energy(More)
The paper presents a control method suitable for reducing effects of nonlinear periodic disturbances on voltage and current. Its focus is on the theory of a modified repetitive control method based on a recurrent integral action procedure distributing the controlled signal in a certain number of intervals and subsequently correcting each interval separately(More)
The paper describes key features and shows some advantages and disadvantages of two measurement approaches used in determination of magnetic properties of soft-magnetic wound cores. The first approach is based on a measuring principle in which the current through the primary winding determines the sinusoidal magnetic flux density in the core and(More)

This paper deals with an improved precision B–H analyzer based on a power amplifier (PA) with a feedback loop, which is suitable for measuring B–H curves and losses of softmagnetic toroidal cores. The theory pertinent to the PA-assisted measurement setup is summarized. The presented system is then upgraded with a correction method that gives it the ability(More)
Povzetek. V prispevku sta predstavljena postopka za brezsenzorsko ugotavljanje začetne lege elektronsko komutiranih motorjev (EKM). Metodi temeljita na merjenju sprememb induktivnosti treh statorskih navitij, ki nastanejo zaradi različne intenzivnosti nasičenja geometrijsko pogojenega magnetnega tokokroga, ob vzajemnem delovanju magnetov na rotorju in(More)
