Abstract-Three-phase pulsewidth-modulated (PWM) boost-buck rectifiers with power-regenerating capability are investigated. The converters under consideration are capable of: 1) both voltage step-up and step-down; 2) bidirectional power processing; and 3) almost unity-power-factor operation with nearly sinusoidal ac current. Expected advantages are: 1) applicability to lower voltage applications, e.g., direct retrofit to replace diode or thyristor rectifiers; 2) switching loss reduction in the inverter load; 3) low-order harmonic control in the inverter load output voltage; 4) blanking time effect mitigation in the inverter load; and 5) a modest level of voltage sag/swell compensation. In this paper, firstly, a step-by-step power stage derivation process is described. Then, taking the Ć uk-Ć uk realization as an example, its operating principle and modulation scheme are described. A steady-state model and dynamic model for controller design are also described. Representative results of circuit simulations and hardware experiments are presented. Through these procedures, the feasibility of the presented three-phase PWM boost-buck rectifier with power-regenerating capability is demonstrated.

“…The boost-buck-based active rectifier has, however, not yet been fully investigated. Although several three-phase boost-buck rectifiers have been reported thus far [13]- [15], none of these offers power-regenerating capability. Although [16] has shown a possible topology, no specific description of its operation has been presented.…”

“…Various single-stage voltage source or current source buckboost inverters without isolation have been derived from Sepic, Ćuk or Zeta dc/dc converters [11]- [17]. To obtain a larger voltage step-up ratio and to realize the electrical isolation, a number of isolated buck-boost converters have also been presented [11]- [14].…”

This paper presents a novel single-stage inverter with high step-up ratio and step-up/down capabilities. A forward-pumping circuit is integrated to the Ćuk-derived voltage source inverter (VSI) to achieve a much higher voltage conversion ratio, while avoiding the use of at larger duty ratio of dc-side switch and modulation index of inverter. The proposed inverter can operate oneself naturally to perform capacitive charging in parallel and discharging in series to give a higher voltage multiple, without increasing dc-side voltage stress and sacrificing ac output voltage step-up/down characteristics. Furthermore, one can adopt lower voltage rating devices to further reduce both switching and conduction losses of dc-side switch. The validity of the proposed inverter is be verified by means of some comprehensive results.Keywords-Single-stage inverter; high step-up ratio.

“…Nevertheless, as far as the total system efficiency is concerned, the resulting efficiency of a two-stage dc/ac converter will be degraded. Hence, many singlestage dc/ac converter topologies such as Z-source/modified Z-source [11], [16], [19]- [25], Sepic,Ćuk, or Zeta-derived dc/ac converters are proposed recently [27]- [34]. However, very few existing dc/ac converters can achieve a high voltage gain while maintaining rather good efficiency.…”

In this paper, a novel high voltage gain single-stage dc/ac converter is proposed for distributed energy resources. A flyback-type auxiliary circuit is integrated with an isolatedĆuk-derived voltage source inverter to achieve a much higher voltage gain. It is seen that through this integration, the capacitors of the flyback and theĆuk circuits are paralleled for charging and in series for discharging automatically. Due to the capacitive voltage dividing, the dc-side switch voltage stress can be reduced and the losses can be reduced as well. Besides, the low influence of coupling coefficient of flyback-type auxiliary circuit on the inverter characteristic renders the proposed inverter design rather flexible and easy. Steady-state characteristics, performance analysis, simulation and experimental results are given to show the merits of the proposed integrated inverter. Finally, based on the same integration concept, a family of different topologies is also presented for reference.Index Terms-Ćuk-derived voltage source inverter (VSI), distributed energy resource (DER), high voltage gain, single-stage inverter.
