“…Thus, conduction and switching losses tend to be less than those in interleaved converts considering the same operating conditions (Balestero et al, 2013). The first high power factor boost rectifier based on the 3SSC was introduced by Bascopé and Barbi (2004), as shown in Figure 15. It is not a bridgeless rectifier, but the reduction of magnetics is possible by the use of the 3SSC, what makes this structure interesting for high-power high-current applications.…”

High power factor rectifiers have been consolidated as an effective solution to improve power quality indices in terms of input power factor correction, reduction in the total harmonic distortion of the input current and also regulated dc voltages. Within this context, this subject has motivated the introduction of numerous converter topologies based on classic dc-dc structures associated with novel control techniques, thus leading to the manufacturing of dedicated integrated circuits that allow high input power factor by adding a front-end stage to switch-mode converters. In particular, boost converters in continuous current mode (CCM) are widely employed since they allow obtaining minimised electromagnetic interference levels. This work is concerned with a literature review involving relevant ac-dc single-phase boost-based topologies with high input power factor. The evolution of aspects regarding the conventional boost converter is shown in terms of improved characteristics inherent to other ac-dc boost converters. Additionally, the work intends to be a fast and concise reference to single-phase ac-dc boost converters operating in CCM for engineers, researchers and experts in the field of power electronics by properly analysing and comparing the aforementioned rectifiers.

Multistate switching cells-based multilevel rectifiers (MLMSR) are a promising technology in power factor correction applications. They are here arranged in a modular structure that is the basis for a Power Electronics Building Block (PEBB). By the implementation of the multi-interphase transformers (MIPT) in a "whiffletree" configuration, multiple cells can be structured in a way that virtually any number of PEBBs can be used to increase a converter rated power. This work presents the conception and development of such a PEBB exemplarily for multi state switching cells multilevel based rectifiers. The proposed PEBB is presented and two lab prototypes are built. Experimental results are presented. I. INTROD UCTIONNowadays, power factor correction rectifi ers are more and more employed in industrial, commercial and residential appli cations to meet power quality standards. Nevertheless, the need for more effi cient equipment, with less weight and volume makes this market even more competitive.Among various topologies, multistate switching cells-based multilevel PFC rectifi ers (MLMSR) have been presented as a promising solution for high efficiency/ high power/ high power density applications [1]- [3]. The advantages of such type of circuits result from the ability to effectively distribute current stresses among the semiconductors, which operates with reduced voltage ratings, at same time that the passive components are reduced, given the natural high frequency mul tiplication at the input and output sides as well the multilevel nature of this converter. The concept of multistate switching cells multilevel rectifi ers is based on the multi-interphase transformer (MIPT) operation (cf. section 11), where the main features of the converter are highlighted when the number of MIPT's windings N increases. However, the increased number of multi-interphase transformer windings makes the converter design very complex, mainly due to the limited availability of adequate magnetic cores to implement the MIPTs.In [4] seven types of multi-interphase transformer confi gu rations are analyzed regarding aspects such as volume, weight and complexity. Particularly, the presented "whiffletree" con figuration is very simple to implement. The overall MIPT with N windings is formed by N -1 simple two windings MIPTs. However, the combinations are limited to N = 2Y, with y = 1,2, 3, 4, .... It should be noted that two windings MIPTs are easily built with conventional EE, toroidal, and other types of cores. This makes the "whiffletree" configuration adequate for the manufacturing of multi state multilevel PFC rectifi ers.Furthermore, the limitation to choose N is minimized when transformers with two and three windings are combined, even though the implementation of three windings transformers is slightly more complex. This distributed cores architecture further improves cooling strategies due to the distribution of losses among multiple magnetic devices. An additional benefi t is naturally obtained from the "whiffletree" confi guration: an ...

“…Moreover, in case of boost PFC converter there is low requirement of filtering because of continuous line current, whereas other dc-dc converters such as buck, buck-boost, and flyback have higher requirement of filtering because of pulsating line current. As boost converter is capable of handling much higher power levels as compared to its other counterparts, much research has been carried out on many different PFC techniques of this topology [1]- [6]. Among all these techniques of improvement of robustness, power efficiency and cost the bridgeless topology has outperformed almost all the techniques.…”

As most of the electronic appliances use DC power so improvement in AC-DC converter is always at large by the researchers. The factors of improvement of power quality are reduction in total harmonic distortion and improvement in power factor at input ac, and tight output dc regulation. In such context, the AC-DC boost converters have gained significant importance, especially when they are used in Continuous Conduction Mode (CCM). This work presents a bridgeless AC DC boost converter operating in CCM. The implementation of input current and output voltage controller is also discussed. Then a comparative analysis based on simulation results of bridgeless and bridge boost rectifier is presented. Bridgeless boost AC-DC converter has outperformed the conventional techniques due to lower conduction losses, lower THD of input current and improved input power factor. I. INTRODUCTIONRectification is a process in which electric power is applications as most of electronics appliances nowadays require DC power. Conventional AC-DC converters, such as Bridge rectifiers, have been developed for this purpose but there are few factors to be controlled in this regard. The Non sinusoidal current drawn at the input side results in lower distortion as well displacement factors. Commanding the line current to follow the line voltage in a sinusoidal manner can gives higher efficiency with improved power factor and lower THD. AC side power factor (PF) is needed to be improved along with lowering of Total Harmonic Distortion of input line current. Tight regulation of the output voltage even in the case of dynamic loads is also a stringent requirement of DC-DC converters. A controller that simultaneously controls both the input as well as the output parameters is the choice. To gain a high power factor, different power factor correction (PFC) techniques have been introduced which can be divided into two parts, passive and active. Passive techniques consist of passive components such as inductors and capacitors that are used as input filter to reduce line current harmonics. However, improvements are not significant and another drawback is the relatively large size of these passive elements. Moreover, these techniques may not be able to handle dynamic loads. On the other hand, active PFC technique is more efficient solution, having a combination of switches and passive elements. Due to presence of switches, controllers can be implemented on active techniques of PFC. At the cost of complexity, the controlled active techniques can increase Power factor and reduce THD in the input AC current. Along with it active techniques can also bring precise DC regulation for variable loads. The active PFC technique uses a diode bridge rectifier followed by a dc-dc converter and the bulk capacitor. By controlling the dc-dc converter, the input line current is commanded to follow the input line voltage and in this way Power Factor approaches to unity. For medium and high power applications boost dc-dc converter works better for power factor corr...
