What is resonant converter? 


Best insight from top research papers

A resonant converter is a type of power converter that utilizes resonant circuits to efficiently convert electrical energy from one form to another. It typically consists of a switching device configuration, a resonant tank circuit, and an isolation transformer. The converter controller generates switching signals for the switching devices based on various error signals, such as voltage error and tank error, to regulate the output voltage. Resonant converters can be designed with different configurations, such as multi-level inverters or switched-capacitor converters, to achieve specific voltage reduction or output adjustment requirements. They can also incorporate features like integrated magnetic elements and spacing grooves to reduce the number and size of magnetic elements, improve power density, and increase power supply efficiency.

What is the mechanism behind resonant tunneling under transverse magnetic fields?5 answersResonant tunneling under transverse magnetic fields involves various mechanisms elucidated in the provided research contexts. The interaction of electrons with different positions of the magnetic oscillator center influences the tunneling current through heterostructures, leading to distinct current-voltage characteristics, transitioning from Z-shaped to N-shaped with increasing magnetic field strength. Additionally, the use of appropriate magnetic vector potential profiles is crucial to avoid artifacts and enhance resonant lifetime and transmission probability in double-barrier structures. In the context of quantum dots, the strong electron-phonon interaction within a quantum dot can break degeneracy, allowing tunneling currents through discrete levels unaffected by temperature, leading to cool electron filtration mechanisms.

What is resonance energy transfer?4 answersResonance energy transfer (RET) is a process where energy is transferred from a donor chromophore to an acceptor chromophore without contact, through Coulombic coupling. RET can occur over long distances if the exchanged photon is waveguided, resulting in enhanced RET rates. The theory of Förster resonance energy transfer (FRET) is widely used to study energy transfer between molecules. FRET efficiency is inversely proportional to the distance between the donor and acceptor, making it highly sensitive to their separation. FRET can be measured using spectrofluorimeters, microplate readers, or fluorescence microscopy, allowing for a wide range of applications in both in vitro assays and live-cell imaging. The general rate theory for resonance energy transfer (gRET) provides a comprehensive framework for incorporating various degrees of freedom and composite states in energy transfer processes. gRET has been applied to study cavity-assisted vibrational energy transfer and has implications for cavity-catalyzed reactions and intramolecular vibrational redistribution.
How does the choice of resonant frequency affect the performance of a DC-DC resonant converter as a battery charger?4 answersThe choice of resonant frequency has a significant impact on the performance of a DC-DC resonant converter as a battery charger. Operating the converter at a high resonant frequency can improve power transfer efficiency and power output capability, especially in dynamic EV charging applications. Additionally, a high resonant frequency enables soft switching characteristics and higher efficiency, which can reduce power loss and increase the overall performance of the charging system. Furthermore, a resonant converter with a wide gain range and bidirectional operation can accommodate the voltage variation of the battery and enable vehicle-to-grid functionalities. The resonant tank parameters and frequency modulation techniques are carefully designed to achieve optimal performance, including high conversion efficiency, minimized circulating losses, and good short-circuit protection. Overall, selecting an appropriate resonant frequency is crucial for achieving efficient and reliable battery charging in electric vehicles.
