“…Research on these phenomena is of great importance in several aspects of engineering, such as analysis about self and mutual inductances [32][33][34][35], stray capacitances [13][14][15][16], power electronics [36] and specially, pulse transformers [37,38]. This paper is arranged as follows: Section 2 shows the basic data of coils and utilized equipments; Section 3 presents discussions about circuit responses and observed phenomena; Section 4 discusses the responses about the inversion of the system; Section 5 presents the conclusions.…”

Abstract-This paper presents a basic analysis about experiment results using planar coils inner ring coils, defining a transformer, when this system is excited by square wave voltage. In this study phenomena of response to step voltage due to parasitic capacitances is analyzed, and a sum of responses when the input square wave frequency increases is given too. These phenomena are uncommon in literature, which can be applied to several areas of researches in electrical engineering, pulse transformers and power electronics.

Abstract-This paper presents an analysis about the results of experiments using planar coils inner ring coils to determine a transformer. The excitation of this system was a square wave voltage, where experiments were realized in two ways: considering planar coil as primary and observing responses on secondary being ring coil (direct system) and the inverse (ring coil as primary and planar coil as secondary-inverted system). In this study, a phenomenon not common in literature on system response is analyzed, showing effects of changes on transfer function in both cases when varying turn numbers of each coil and several variations on responses due to changes on resistances, parasitic capacitances, self and mutual inductances of the coils. The uncommon phenomenon appears as modulated response on specific turn ratio. The obtained results can be used to researches in areas as power electronics and pulse transformers.

“…Many research results focusing on the control strategies have been presented. In these control strategies [7][8][9][10][11][12][13] , the output dc voltage is controlled by a voltage loop, where a voltage PI regulator acts on the dc voltage error to generate references for the ac currents in the stationary (a-b-c or α-β) or rotating (d-q) frames. PI regulators of the current loop ensure that the input ac currents track their references.…”

This paper studies the control strategies of three-phase high power factor PWM rectifier. The mathematical model for the rectifier is analyzed in detail. The control strategies in synchronously rotating d-q frame and two-dimensional stationary (α-β) frame are introduced respectively. By analyzing the control procedure in mathematics and the simulation results of MATLAB, the paper analysis two typical control strategies and indicates the relative merits of them. Finally, the experimental prototype of the three-phase PWM rectifier using the predictive current control strategy is designed in laboratory, and the results are provided to verify the superiority in high power factor PWM rectifier.
