“…Another two element RC called the parallel resonant converter (PRC) offers high impedance at resonant frequency and so it is suggested for induction heating application [19]. Similar overview of other series-parallel RCs in three and four element forms is presented in [20] and [21]. It is evident that, identifying the characteristics of a RC is an essential prerequisite in selecting a topology for specific application.…”

Resonant converters (RCs) are perceiving global interests of the research community for its eminent contribution in design of many industrial and commercial applications. Rich literature and well-established technology is available to define the role of RCs in such applications where the load is predominantly passive and resistive. However in applications like charging, the nature of load is often interpreted as capacitive and the knowledge on how a RC reciprocates to such variable, non linear load is limited. Motivated by this, the paper investigates about 25 capacitive loaded resonant structures and each of them is thoroughly analyzed to evaluate various key parameters like the output current, peak input current, and current gain. A comparative study is done to categorize and organize these topologies in regard to each of the said parameters. This provides a quick overview of various resonant converter topologies and helps designers to choose a structure that may fit their application. To this base knowledge, the study is further narrowed down to find suitable topology for charging application and accordingly proposed a novel fourth-order RC topology called LA7. A hardware prototype was built to compare and validate the simulated and measured performances.

“…There are thirty-six separate third-order RTN tanks [80,89,92]; some of them consist of two capacitors and one inductor, while others are opposite shaped, as shown in Figure 20a-d. Three-element RTN resonant converters have been widely used in many industries, such as in LLC, LCC, CLL, LCL, and hybrid series-to-parallel resonant converters (RCs) [93][94][95][96]. LLC and LCC are the commonest forms of third-order RTN converters.…”

With the rapid development of modern energy applications such as renewable energy, PV systems, electric vehicles, and smart grids, DC-DC converters have become the key component to meet strict industrial demands. More advanced converters are effective in minimizing switching losses and providing an efficient energy conversion; nonetheless, the main challenge is to provide a single converter that has all the required features to deliver efficient energy for different types of modern energy systems and energy storage system integrations. This paper reviews multilevel, bidirectional, and resonant converters with respect to their constructions, classifications, merits, demerits, combined topologies, applications, and challenges; practical recommendations were also made to deliver clear ideas of the recent challenges and limited capabilities of these three converters to guide society on improving and providing a new, efficient, and economic converter that meets the strict demands of modern energy system integrations. The needs of other industrial applications, as well as the number of used elements for size and weight reduction, were also considered to achieve a power circuit that can effectively address the identified limitations. In brief, integrated bidirectional resonant DC-DC converters and multilevel inverters are expected to be well suited and highly demanded in various applications in the near future. Due to their highlighted merits, more studies are necessary for achieving a perfect level of reducing losses and components.

“…Resonant BBC topology that operates with ZVS or ZCS can be implemented by adding an LC circuit to BBC conventional topology. Further details can be consulted in [51][52][53][54][55][56][57][58][59][60][61][62][63]. The aforementioned resonant LC circuit requires an additional switch (a second one) to introduce an inductor to the converter circuit for providing an additional path with zero impedance where the current and voltage do not strongly change their values.…”

PFC Single-Phase AC/DC Boost Converters: Bridge, Semi-Bridgeless, and Bridgeless Topologies

et al. 2021

View full text Add to dashboard Cite

Power Factor Correction (PFC) single-phase AC/DC converters are used in several power electronics applications as full wave control rectifiers improving power quality and providing high standards of efficiency. Many papers dealing with the description or use of such topologies have been published in recent years; however, a review that describes and organizes their specific details has not been reported in the technical literature. Therefore, this paper presents an extensive review of PFC single-phase AC/DC converters operating with the Boost converter topology for low and medium voltage as well as and power appliances. A categorization of bridge, semi-bridgeless, and bridgeless, in accordance with the construction characteristics, was carried out in order to unify the technical terminology. Benefits and disadvantages are described and analyzed in detail. Furthermore, a comparison performance in terms of PFC, Total Harmonic Distortion (THD), power capacity, electromagnetic compatibility (EMC), number of elements, and efficiency is included.
