Abstract-This paper presents a new analytical method for the generalized study of a cluster of single-stage power-factor correctors (S 2 PFCs). Due to this generalized approach, new topologies have been obtained, and the study of other known topologies has been simplified. The new analytical method simplifies the design of S 2 PFCs by making it possible to compare a large number of different designs from the same viewpoint in order to identify the best topology. Finally, this research has enabled us to reduce the total size of the additional inductors that are used by a factor of two to three with respect to previous implementations.

“…The solution in Fig. 2(g) was presented in [10] as the "magnetic switch" and in [12] as the "bus-voltage feedback." High-frequency diodes are not necessary in these solutions, given that the filter inductor works in DCM and there is an input rectifier with fast diodes (see Fig.…”

“…5(a)-(c) obtains the dither signal with a tertiary winding on the transformer of its cascaded power stage. Although it has been shown [49] that these SSC's yield higher efficiency and have lower component stress over the type of SSC's shown in Fig. 7, the output voltage will be partly modulated by the rectified line voltage due to loading effect.…”

Principle of synthesizing single-stage converters (SSC's) for off-line applications is presented in the paper. The principle is primarily based on the concept of dither effect, from which power factor corrector (PFC) cells comprising energy buffers and high frequency dither signals are introduced. Properly selecting an eligible PFC cell and inserting it in between input rectifier and dc-link capacitor can yield an SSC. In the paper, principle and configuration of PFC cells are addressed; thus, quite a few families of SSC's for off-line applications can be synthesized from the derived PFC cells. With this principle, not only the SSC's discussed in literature can be developed alternatively, but novel SSC's can be synthesized. Most of the SSC's have been proved in the literature to be feasible in applications with moderate power levels.

“…Among the single-stage circuits, a number of circuits described in [31, [51, [7], and [SI seem particularly attractive because they can be implemented with only one semiconductor switch and a simple control. Except for the circuit in [7], all other S41CS circuits employ the DCM operation in the ICs stage, mostly with boost topology.…”

“…Except for the circuit in [7], all other S41CS circuits employ the DCM operation in the ICs stage, mostly with boost topology. In fact, in these circuits, low input-current harmonic distortions are achieved through the inherent property of the DCM boost converter to draw a near sinusoidal current if its duty cycle during a line period is held relatively constant.…”

Single-stage, single-switch, isolated power supply technique with input-current shaping and fast output-voltage regulation for universal input-voltage-range applications

A new single-stage, single-switch, input-currentshaping (S41CS) technique which combines the boost-like inputcurrent shaper with a continuous-conduction-mode dc/dc output stage is described. In this technique, the boost inductor can operate in both the discontinuous and continuous conduction modes. Due to the ability to keep a relatively low voltage (< 450 Vdc) on the energy-storage capacitor, this technique is suitable for the universal line voltage applications. The voltage on the energy-storage capacitor is kept within the desirable range by the addition of two transformer windings. The principle of operation of the S41CS circuit with forward dc/dc converter is presented. Experimental results obtained on a 100-W (5-V/20-A) prototype circuit are also given.
