Resonant Power Converters for Renewable Energy Applications: A Comprehensive Review

Abstract

Studies on resonant power converters (RPCs) have received much attention due to the rapid growth of their potential in modern power and renewable energy applications such as photovoltaic, electric vehicles, wind, and fuel cells. Consequently, a significant number of studies focusing on RPC topologies for renewable energy applications is available. Generally, these studies have addressed several aspects, such as the development of their soft switching feature, smooth waveforms, high power density, and high efficiency. With this in mind, the present paper aims to review the development of the RPCs, challenges in their development, and comparison between common topologies as highlighted in literature. In addition, the use of RPCs in various applications of renewable energy is highlighted, focusing on some of the recently utilized topologies based on their constructions and achievements. There are still several issues and challenges in research that need to be considered for future improvement of the RPC performance in renewable energy applications. The improvement may require modifications on the circuit design or control strategies.

A Comprehensive Review on Charging Topologies and Power Electronic Converter Solutions for Electric Vehicles

“…Additionally, the review papers have deliberated the control strategies for DC-DC converters in terms of parameters, control variables (terminal cell voltage, capacity, SOC), and control algorithms (high-level or low-level). These discussions are supported by the compari-son with relevant studies [13], [21], [22], [88], [90], [98], [105]- [107].…”

“…To cope with the restrictions of the DC-DC converters such as switching losses, size, and electromagnetic interference (EMI), resonant converters and multiport converters (MPCs) have been extensively implemented in high-voltage EV applications depending on the number of reactive elements and independent voltage sources [22], [31], [32].…”

“…[13], [21] [12], [22] Study in detail state-of-the-art EV charging topologies and PEC solutions for EV applications from the point of view of their groupings, configurations, control methods, and future research projections and their impacts on the power quality of the utility grids based on recent review papers DC-AC converters, and AC-AC converters are required to be implemented to sustain high efficiency, reliability, and operational performance [37], [38], [40], [47]. Focusing on DC-AC converters, they achieve high power density without excessive switching losses.…”

An Extensive Critique on Electric Vehicle Components and Charging Systems

“…erefore, this converter with the soft switching methods is applicable for the battery charging applications in EV [108]. Nonetheless, the resonant converter has some limitations like heating and complex design of transformer [109]. A modified resonant converter using gallium nitride (GaN) switches was developed for electric vehicles in [110].…”

Design Methodology and Analysis of Five-Level LLC Resonant Converter for Battery Chargers

“…As mentioned earlier, the conventional topologies for realizing resonant converters are half-bridge and full-bridge, and multilevel inverters are not favorable for high-frequency resonant inverters since modelling them for control design is difficult, particularly when using high-frequency switching modulation approaches. To eliminate the drawbacks associated with half-bridge [6], full-bridge [40], phase-shifted full-bridge [41], and threelevel [36] inverters integrated with resonant tank network, a five level multilevel inverter is introduced in this paper.…”
