“…For example in [7] the power factor is highly dependent of the duty cycle. At 110 Vrms the power factor of the proposed rectifiers is 0.999, which is a better result when comparing to other approaches such as [9] and [10]. This also shows the effectiveness of this current control system.…”

“…Unlike the boost type ac-dc PFC converter, the buck type PFC has the capability to limit the inrush and dc short-circuit currents, but has step-down characteristics, since the output voltage of the rectifier is always lower than the peak voltage value of the input ac sources [7]- [10]. The step-down action can prevent the use of the buck design in some applications.…”

This paper presents two topologies for single-stage single-phase double-buck type PFC converters, designed to operate at high power factor, near sinusoidal input currents and adjustable output voltage. Unlike the known buck type PFC topologies, in which the output voltage is always lower than the maximum input voltage, the proposed converters can operate at output voltages higher than the ac input peak voltage. A reduced number of switches on the main path of the current are another characteristic of the two proposed topologies. To shape the input line currents, a fast and robust controller based on a sliding mode approach is proposed. This active non-linear control strategy, applied to these converters allows high quality input currents. A Proportional Integral (PI) controller is adopted to regulate the output voltage of the converters. This external voltage controller modulates the amplitude of the sinusoidal input current references. The performances of the presented rectifiers are verified with experimental results.

SUMMARYThe duality principle is applied to derive new single-stage power-factor-correction (PFC) voltage regulators. This paper begins with an application of duality transformation to conventional discontinuousconduction-mode buck, buck-boost and boost converters. The resulting dual converters operate in the discontinuous capacitor voltage mode. These new converters provide the same PFC property, but in the dual manner. It is proved that in the practical case of the input being a voltage source, the mandatory insertion of inductance between the voltage input and the 'dual PFC converter' does not a ect the power-factor-correcting property. A new single-stage PFC regulator is derived by taking the dual of a well-known circuit based on a cascade of conventional boost and buck converters. Analytical design expressions are derived, illustrating the relation between current stress and component values. Experiments are performed to conÿrm the operation of the circuit and its power-factor-correcting capability.

“…3 where the capacitor C operates in DVM. The analysis of this dc model was originally published in [7] and a part of that analysis is presented here, and will be further extended to three-phase ac-dc buck-type converters in which input capacitors also operate in DVM. The key switching waveforms of the converter are shown in Fig.…”

This paper proposes a three-phase, two-switch, buck converter that can operate with input power factor correction. The key features of the proposed converter are that a switch in it can operate with almost half the voltage stress of that in the standard three-phase, single-switch buck converter and with less current stress. In the paper, the operation of the converter is discussed and a detailed mathematical analysis is performed to determine its steady state characteristics. The results of the analysis are also used to design the converter using a procedure that is explained in detail. The feasibility of the proposed converter is confirmed with results obtained from an experimental prototype.
