“…The impact of the number of converter channels on the quality of power grid currents can be evaluated on the basis of the i ε error. This one is related to the difference of a i A (i B , i C ) current and its 1 st harmonics -similarly to the converter control error (8). A value of this error is a function of both, the rectifier output power DC P and M:…”

“…The following way relies on the use of an active rectifier, which is built with a transistor inverter switching at frequency, being several times higher than frequency of voltage in a power grid [3,6]. Other proposed solutions use the PFCs based on multi-level converters [7,8]. Also, to correct the waveform of the power grid current the rectifier built with diodes (or thyristors) being interconnected by means of coupled inductors can be used [9].…”

Abstract:In the paper the 3-phase power diode rectifier system with quasi-sinusoidal input (power grid) current is presented. In order to benefit from it, the current modulation in the DC circuit of a rectifier is used. The essential part of the current modulator is the wide-band power electronics controlled current source based on a multi-channel converter. The control algorithm of the current modulator respects impact of aliasing phenomena at system stability by using the method proposed by the authors. The paper includes the rectifier system description and rules of operation of the current modulator. Also, some results of research on both the rectifier simulation model and the laboratory prototype of a current modulator are presented.

“…Resonant converters (RCs) have been a potential candidate in many power electronics applications involving high-frequency power processing such as dc-dc converters [1], high voltage power supplies [2], power factor correction [3], electronic lamp ballasts [4], induction heating [5], etc. The merits of RCs include soft switching, high frequency operation, high efficiency, small size, gainful utilization of the circuit parasitic components, etc.…”

Resonant immittance converter (RIC) topologies can transform a current source into a voltage source (Type-I RICs) and vice versa (Type-II RICs), thereby making them suitable for many power electronics applications. RICs are operated at a fixed frequency where the resonant immittance network (RIN) exhibits immittance conversion characteristics. It is observed that the low-frequency response of Type-II RINs is relatively flat and that the state variables associated with Type-II RINs affect the response only at the high frequencies in the vicinity of the switching frequency. The overall response of a Type-II RIC is thus dominated by the filter response, which is particularly important for the controller design. Therefore, an approximate equivalent circuit model and a small-signal model of Type-II RICs are proposed in this paper, neglecting the high-frequency response of Type-II RINs. While the proposed models greatly simplify and speed-up the analysis, it adequately predicts the open-loop transient and small-signal ac behavior of Type-II RICs. The validity of the proposed models is confirmed by comparisons of their results with those obtained from a cycle-by-cycle simulation and with an experimental prototype.

“…These cheaper and simpler converters are widely used in industry and their properties and characteristics have been well established. Research on the topic of higher power ac-dc single-stage full-bridge converters, however, has proved to be more challenging, and, thus there have been much fewer publications [12]- [14].…”

In this paper a new three-level single-stage powerfactor-corrected ac/dc converter is presented. The proposed circuit integrates the operation of a boost power factor correction converter and a three-level dc/dc converter into one converter. It does not have the problem of high rising intermediate bus voltages at light load conditions that other single-stage converters have and can operate over a wider load range with significantly less output inductor current ripple; moreover, its input current has little distortion. In the paper, the operation of the new converter is explained in detail and analyzed, its steady-state characteristics are determined, and its design is discussed. Experimental results obtained from a prototype are presented to confirm the feasibility of the new converter.
